The methodology consists of a multimedia model that addresses the transport of a chemical in groundwater, surface water, soil erosion, the atmosphere, and accumulation in the food chain. The methodology is intended for use as a screening tool. NOTE: For convenience, the terms "MMSOILS model system" or "MMSOILS" will be used in this document to refer to the MMSOILS model and all associated support files and programs as a single unit. Therefore, the terms "MMSOILS" and "MMSOILS Model System" are synonymous for purposes of this document. _________________________________________________________________ ABSTRACT Refer to file ABSTRACT.TXT for an abstract of the MMSOILS model system (refer to FILE NAME AND CONTENT section). _________________________________________________________________ DOCUMENTATION Copies of the following documents are included on the distribution diskettes and within the Internet distribution file INSTALMS.EXE.

This model system is designed for the IBM PC family of microcomputer or compatible systems running under version 3.30 or higher of the Microsoft or PC Disk Operating Systems (PC or MS DOS--refer to DEVELOPMENT SYSTEM section). Properly configured, this model system and its support files and programs can be executed under PC DOS or MS DOS 3.30 and later versions, DOS 4.0x, DOS 5.0x, or DOS 6.x. To install the MMSOILS model system and/or related support files and programs on a hard disk, insert the first distribution diskette in a compatible diskette drive. Type A:\INSTALL or B:\INSTALL at the DOS system prompt and press the key. Then follow instructions and respond to the prompts presented on the monitor screen by the interactive installation program. This is a compressed, self-extracting, interactive installation program-- with on-line, context sensitive help--that contains the MMSOILS model system (MMSOILS, Version 4.00), dated June 1997. NOTE: If the MMSOILS model system is being installed from the MMSOILS installation file (INSTALMS.EXE) down loaded from the Internet, then the user should type INSTALMS at the DOS system prompt and press the key. This command assumes that the current default drive and sub-directory is the same drive and sub-directory that contain the file INSTALMS.EXE. For further information and to access CEAM software products through the Internet, refer to the TECHNICAL HELP CONTACT section. NOTE: The content of the distribution diskettes can be copied to another set of "backup" diskettes using the DOS DISKCOPY command. Refer to the DOS Reference Manual for command application and use. The "backup" diskettes must be the same size and storage density as the original source diskettes. The following FILE NAME AND CONTENT section provides a brief functional description of each file by name or file name extension type. Other sections in this document contain information about o system development tools used to build the microcomputer release of the MMSOILS model system o recommended hardware and software configuration for the execution of the model system and all support programs o program execution o minimum file configuration o program modification o technical support _________________________________________________________________ FILE NAME AND CONTENT The self-extracting, interactive, installation executable program file exists in a compressed format to save disk space and file transfer time. This document contains a description of each file that can be decompressed from the compressed distribution diskettes and/or file. Follow the instructions shown on the interactive installation program screens and menus to install, decompress (extract), and restore file(s) to their original name and size in order to place the MMSOILS model system in a usable format on a hard or virtual disk. For comparison purposes, the original date and time of creation are also restored with each file. NOTE: Execution of the INSTALL or INSTALMS command can extract one or more MMSOILS model system files. These files are automatically stored into DOS sub-directories on the hard disk. The hard disk and sub-directory structure, under which the sub-directories shown below are stored, is selected by the user (e.g., C:\MMSOILS) during execution of the INSTALL or INSTALMS program. The string "InstallationDirectory" will be used to denote the highest level default installation directory structure chosen by the user during execution of INSTALL or INSTALMS. Below the installation directory, all files are grouped and listed by the appropriate DOS sub-directory name into which they will be automatically stored. ** Sub-directory InstallationDirectory\README: NOTE: The following files are ASCII text (non-binary) files that can be displayed on the monitor screen with the DOS TYPE command or printed using the DOS PRINT command. READ.ME - MMSOILS model system execution and general support guide. RELEASE.TXT - Summary of corrections and/or changes between release versions.

For further information, refer to the MINIMUM FILE CONFIGURATION section. NOTE: The following files are the MMSOILS Users' Manual files. The complete documentation is contained within the following binary, non-ASCII files; *.EPS (Encapsulated Post Script), *.WP6 (WordPerfect 6.x), *.DOC (MicroSoft Word 6.0), *.XLS (MicroSoft Excel); and the following non-binary, ASCII files; *.TXT. All files should only be viewed and/or printed within WordPerfect 6.1 or greater. *.WP6 - MMSOILS: Multimedia Contaminant Fate, Transport, *.EPS and Exposure Model Documentation and User's Manual *.TXT Version 4.0 *.XLS TAB11_21.DOC ** Sub-directory InstallationDirectory: F77L3.EER - Run time error message library file for Lahey FORTRAN (F77L3) (refer to DEVELOPMENT SYSTEM section). This file is read automatically during execution of the MMSOILS model system executable task image file (*.EXE) if an error is detected during execution. RETURN1.ANS - An empty file containing a single carriage return character used to provide an key or null response to an input prompt in selected DOS batch command files. MMSOOPEN.SCR - Initial welcome and CEAM information screen displayed before the execution of the MMSOILS model via the DOS batch command file MMSOILS.BAT. This is an ASCII text (non-binary) file that can be displayed on the monitor screen with the DOS TYPE command or printed using the DOS PRINT command. NOTE: To execute a DOS batch command file (*.BAT)--and hence a model or program spawned (i.e., executed) buy a given batch command file--from any sub-directory located on a hard or virtual disk drive, try adding the MMSOILS installation sub-directory (e.g., C:\MMSOILS) to the DOS search PATH and copy other appropriate run time support files to the current default sub- directory. One way to accomplish this is to add or modify the PATH statement in the system start-up file, AUTOEXEC.BAT (located in the root directory on the start-up or boot drive). For example PATH C:\;C:\DOS;C:\UTIL;C:\WP51;C:\MMSOILS; Refer to the DOS Reference Manual for PATH command and AUTOEXEC.BAT file application and use. MMSOILS.BAT - DOS batch command file used to execute the MMSOILS model. To execute, type MMSOILS at the DOS system prompt, then press the key. For further information, refer to the ROUTINE EXECUTION section. WARNING: Executable task image file (*.EXE) should only be executed using the corresponding DOS batch command file provided (*.BAT). XMMSOILX.EXE - Executable task image file for the MMSOILS model. NOTE: All MMSOILS model input data and output listing files are ASCII (non-binary) text files that can be displayed on the monitor screen with the DOS TYPE command or printed using the DOS PRINT command. These files can also be viewed or edited using any editor program that can read and save a file to disk in ASCII text (non-binary) format. NOTE: An input or output file name path specification and/or file name, as typed at a run time prompt by the user, must be a unique and valid DOS path and/or file name. An input data file name must also be a valid MMSOILS file name -- either furnished with the distribution package or created, designated, and named by the user. A file name used as input data for the MMSOILS model will be processed and executed in the run of the model. Remember, a DOS file name can be from 1 to 8 characters and can have an optional 1 to 3 character file name extension. NOTE: Refer to the explanation of the OUTPUT\*.EX? files for a procedure to compare the contents of an output file produced by the MMSOILS model on the users system (*.123) to an output file provided through the distribution package. To execute the MMSOILS model, the user must first create and enter the necessary input data into input data files (*.123). These files should only be created and/or modified using an editor program that can read and save a file to disk in ASCII text (non-binary) format. NOTE: For further explanation, information, and listings of example input and output data files, refer to Appendix D of the User's Manual. *.EX? - Five sets of example input data files to test the installation and demonstrate application of the MMSOILS model. These data files are also furnished to provide instruction by example and can be used as templates for the preparation of a new or modified input file set. To test the installation, execute the MMSOILS model using each file set, in numerical sequence, as the name of the input data files. These files provide examples of the input for most sections and capabilities of the MMSOILS model. For further information on executing MMSOILS, refer to file MMSOILS.BAT in this section or refer to the ROUTINE EXECUTION section. Sub-directory InstallationDirectory\OUTPUT: NOTE: The symbol "" represents pressing the or carriage return key. Responses and key strokes that can be typed by the user are underlined with the hyphen character (-) and/or enclosed by the angle bracket characters (<>). *.EX? - Output listing file sets produced by execution of the MMSOILS model using the test input data files provided. After executing the MMSOILS model using each test input data file set (*.EX1, *.EX2, *.EX3, *.EX4, and *.EX5), compare the contents of the file produced (e.g., SURFOUT.123) in the MMSOILS default sub-directory (e.g., C:\MMSOILS) with the corresponding output file provided and stored within the sub-directory OUTPUT (e.g., C:\MMSOILS\OUTPUT\SURFOUT.EX1). To compare file contents, use the COMP (PC DOS) or FC (MS DOS) file compare command, or print both files then compare contents by hand. For further information on executing the MMSOILS model, refer to file MMSOILS.BAT in this section or the ROUTINE EXECUTION section. Example MMSOILS execution and file comparison sequence: 1) Set the default drive to the disk containing the MMSOILS model system sub-directory: A:\> C: -- 2) Change the DOS default sub-directory to the sub-directory designated by the user during the installation program as the installation sub-directory (e.g., MMSOILS). Use the DOS CD (change directory) command at the DOS system prompt: C:\> CD \MMSOILS ----------- 3) Copy one of the five example input data file sets to a file name designation (i.e., *.123) needed by the MMSOILS model: C:\MMSOILS> COPY *.EX1 *.123 ---------------- 4) Execute the MMSOILS model with the selected test input data file set: A) C:\MMSOILS> MMSOILS ------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (Initial MMSOILS banner/registration screen displayed here...press key to clear screen and continue model execution...) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (Next, the following screen is displayed while the MMSOILS program is loaded into memory...) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # #----------------------------------------------------------------------# ## Executing MMSOILS DOS command file. #----------------------------------------------------------------------# # # ## Loading MMSOILS model task image file...wait. # #-------------------------# ## MMSOILS run beginning. #-------------------------# # ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ» º 32-bit Power for Lahey Computer Systems º º Phar Lap's 386|DOS-Extender(tm) Version 4.1L º º Copyright (C) 1986-92 Phar Lap Software, Inc. º º Available Memory = xxxxx Kb º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (Where xxxxx is a number that represents the available RAM memory on the host system expressed in K bytes (K=1,024).

This file, as noted below with the file name, can be cleaned up (i.e., deleted) at any time by the user. NOTE: The following file is not distributed with the distribution release. It is created and/or updated (appended to) automatically when the user executes the MMSOILS model system DOS batch command files (*.BAT). This fileswill be stored in the sub-directory selected by the user during the installation of the MMSOILS model system. MMSO_RUN.LOG - Run time log file that contains a beginning and ending date and time stamp for each execution of the MMSOILS model. Refer to the ROUTINE EXECUTION section for further information. This file can be cleaned up (i.e., deleted) at any time by the user. ** Sub-directory InstallationDirectory\MMSOCODE: NOTE: All FORTRAN source code files (*.INC, *.FOR) and "make" command files (MAKEFILE) are NOT required to document, execute and/or test any model, program, or associated run time support file as provided on the distribution diskettes or the Internet installation file. For further information, refer to the MINIMUM FILE CONFIGURATION section. MAKEFILE - Lahey "make" file that can be used to compile and/or link edit the MMSOILS model FORTRAN source code files (*.INC, *.FOR) to incorporate changes made in the source code files by the user. Refer to the program listing for in-code documentation. The execution of this command can produce a new executable task image file (XMMSOILX.EXE) for the MMSOILS model. This command file only needs to be executed if changes have been made in the FORTRAN source code, not an input/output data file. To execute, type MAKE at the DOS system prompt, then press the key. *.INC - FORTRAN source code "include" files containing FORTRAN COMMON block declarations for the MMSOILS model source code. These files are automatically included or copied into FORTRAN source code files (*.FOR) during compilation as executed by the corresponding "make" (MAKEFILE) file. *.FOR - FORTRAN source code files for the MMSOILS model, version 4.00. _________________________________________________________________ DEVELOPMENT SYSTEM The following list describes the language and program development tools used by the U.S. EPA Center for Exposure Assessment Modeling to build version 4.00 of the microcomputer implementation of the MMSOILS model system. Also shown are the recommended minimum hardware and software configuration and the recommended \CONFIG.SYS configuration/environment file statements for the implementation and execution of this model system and all related support files and programs. Make sure that the IBM PC or compatible system has these statements in the \CONFIG.SYS file, and re-boot the system to implement these changes before attempting to install or use the MMSOILS model system. Development System: Hardware System: Fully IBM compatible 80386, 80486, or 80586 Language: FORTRAN 77 Operating System: DOS version 3.30 or higher. Properly configured, this model system should also work on hardware platforms with PC DOS or MS DOS versions 4.0x, 5.0x, or 6.x.

Printer Software: For *.WP6 files only, WordPerfect version 6.1 or greater. _________________________________________________________________ ROUTINE EXECUTION NOTE: The symbol "" represents pressing the or carriage return key. Responses and key strokes that can be typed by the user are underlined with the hyphen character (-) and/or enclosed by the angle bracket characters (<>). NOTE: It is possible that the MMSOILS model system could be incompatible with MS DOS and Windows software cache files SMARTDRV.SYS or SMARTDRV.EXE loaded from the system configuration files \CONFIG.SYS and/or \AUTOEXEC.BAT on the boot drive. If any portion of the MMSOILS model system prematurely halts, produces unusual results, and/or causes the host system to halt or hang, remove any SMARTDRV statements on the boot drive \CONFIG.SYS and/or \AUTOEXEC.BAT files, then re-boot the system to implement these changes before attempting to reuse any portion the MMSOILS model system. Introduction ~~~~~~~~~~~~ Complete the installation process to make the full or any portion of the MMSOILS model system and related files resident on a hard (usually designated as "C:") or virtual disk drive. Then modify the \CONFIG.SYS system environment file and restart the microcomputer system. This needs to be completed only once for a given installation and/or execution of the MMSOILS model system. DOS Storage Path ~~~~~~~~~~~~~~~~ Verify that the MMSOILS model system executable task image file (*.EXE), DOS batch command files (*.BAT), other run time support files, and user defined input data and/or command file(s) are in the current default DOS sub-directory. It is convenient but not required to have these files in the same sub-directory. NOTE: To execute a DOS batch command file (*.BAT)--and hence a model or program spawned (i.e., executed) buy a given batch command file--from any sub-directory located on a hard or virtual disk drive, add the MMSOILS installation sub-directory (e.g., C:\MMSOILS) to the DOS search PATH and copy other appropriate run time support files to the current default sub- directory. One way to accomplish this is to add or modify the PATH statement in the system start-up file, AUTOEXEC.BAT (located in the root directory on the start-up or boot drive). For example PATH C:\;C:\DOS;C:\UTIL;C:\WP51;C:\MMSOILS If any portion of the MMSOILS model system prematurely halts, produces unusual results, and/or causes the host system to halt or hang, copy all DOS batch and other run time support files from the MMSOILS model system installation sub-directory to the current default sub- directory from where the MMSOILS model system is being executed via the DOS search PATH statement. Refer to the DOS Reference Manual for PATH command and AUTOEXEC.BAT file application and use. Routine Execution Steps ~~~~~~~~~~~~~~~~~~~~~~~ Step Description/Action ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1) Set the default drive to the disk containing the MMSOILS model system sub-directory. For example: A:\> C: -- 2) Change the DOS default sub-directory to the sub-directory designated by the user during the installation program as the installation sub-directory (e.g., MMSOILS). Use the DOS CD (change directory) command at the DOS system prompt: C:\> CD \MMSOILS ----------- NOTE: A common problem is for a DOS executable or batch command file (*.EXE, *.BAT) to be unable to locate a file because it assumes the file is on the default drive and/or sub-directory when it is not. If input and/or other run time support file(s) are not on the default drive and sub-directory, the user can type a drive and/or path name ahead of the file name. For further information refer to the "File Name and Path Specifications" sub-section later in this document or the DOS Reference Manual. 3) To execute the MMSOILS model, type: C:\MMSOILS> MMSOILS ------- After an opening banner/registration screen is displayed on the monitor, press the key to clear the screen and begin model execution. NOTE: The MMSOILS model system is a DOS, not Windows, application and should be executed from a DOS command line prompt. NOTE: To execute the MMSOILS model, the user must first create and enter the necessary input data into input data files (*.123). These files should only be created and/or modified using an editor program that can read and save a file to disk in ASCII text (non- binary) format. Viewing Output Results ~~~~~~~~~~~~~~~~~~~~~~ After executing a MMSOILS model system executable task image file, exiting MMSOILS, and returning to the DOS prompt, the user can view an output file (*.123), if any, produced by the execution of a program or model if and only if that file is in ASCII text (non-binary) format. Results can be viewed by scrolling through the output file that was (1) a result of model or program execution and/or (2) named by the user at a run time prompt. A word processor or text editor is convenient for this purpose, or the command TYPE filename | MORE can be used where "filename" is the name of the output file. However, the TYPE command is awkward for a file that exceeds the 80-column screen width. Alternatively, the output file can be printed. A compressed print mode (132 column) should be used to avoid awkward--wrapped around--output from lines that exceed 80 columns. The DOS MODE command can be used for this purpose. For a parallel printer assigned to LPT1, the DOS command MODE LPT1: 132 will cause most printers to print in compressed mode. For further information, refer to the DOS Reference Manual. File Name and Path Specifications ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A file name, path specification, and/or the parameter file name argument "filename" must be a unique and valid DOS path and/or file name. The user response "filename" must also be a valid MMSOILS model system command, input, or output file name -- either furnished with the distribution package (refer to FILE NAME AND CONTENT section) or created, designated, and named by the user. A file name used as input data for a program or model in the MMSOILS model system will be processed and executed in that run of the program or model. In general, file names used for input data, command, and/or output listing files (except for the test input and example output cases provided) are arbitrary, but must follow the rules for DOS file names. A file name should assist the user with identifying the contents or purpose of a file (e.g., INPUT.DAT, OUTPUT.LST). However the MMSOILS model uses specific file names for input and output data (refer to the *.EX? files within the installation and OUTPUT sub-directories) and a specific file name extension for all input and output files (*.123). Any DOS file name can be from 1 to 8 characters and can have an optional 0 to 3 character file name extension. Any characters beyond 8 in the file name or beyond 3 in the file name extension will be truncated and ignored by the DOS operating system. Refer to the DOS Reference Manual for further information on file names and disk file input/output procedures, rules, and commands. _________________________________________________________________ RUN TIME AND PERFORMANCE The following run times (approximate) were observed using the test input data file sets furnished with the distribution version of the MMSOILS model system. Remember that these times were obtained using input test data files that may not be representative of a "real world" problem and/or data. The test data files have been furnished for testing the installation of the MMSOILS model system and for instruction by example. In general, these input test data files are not intended to be representative of full scale model simulations. They were developed to test the installation of significant sections of model code. The run times listed in the table below were produced on a Microway 80486 B2T EISA class microcomputer running under MS DOS 6.0 and using 640k bytes of random access (low end) memory (RAM), 32 megabytes of extended memory, a 32 megabyte virtual (RAM) disk, Microp 1624-15 SCSI 765 megabyte DPT EISA hard disk with a 12K byte cache SCSI controller, a 256K byte memory cache, a 66 megahertz clock, a Number Smasher-860 40 megahertz, 32 megabyte math numerical coprocessor, and an ATI Ultra Graphics 1 megabyte video card. ** MMSOILS Model System Test Runs Input Data File Name Set Approx.

CEAM operates a UNIX Listserver mailing list system. The name of the list is CEAM-USERS. Listserver is an automated mailing list system. A user can add him/her-self to a selected mailing list, post messages, and/or review/read messages. Lists can be moderated (owner decides which messages are made public) or un- moderated (all incoming messages are posted). Listserver is best suited for e-mail discussion groups. It is not a file service such as for the distribution of CEAM software products. This listserver broadcasts up-to-date information concerning CEAM software products, activities, and events. This includes announcements for CEAM and/or non-CEAM supported workshops and training sessions; software product version release, updates, and documentation information; hints on software installation, operation, application, problems, and/or enhancements; and the exchange of information quickly among users, and between users and CEAM support personnel. NOTE: The CEAM-USERS list is not moderated. To subscribe, execute a mail service to send the following information: NOTE: The symbol "" represents pressing the or carriage return key. Responses and key strokes that can be typed by the user are underlined with the hyphen character (-) and/or enclosed by the angle bracket characters (<>). mail listserver@unixmail.rtpnc.epa.gov -------------------------------------- Subject: (i.e., leave subject line blank) subscribe CEAM-USERS yourfirstname yourlastname ----------------------------------------------- The user can also check the status of this model system or any other CEAM software product through Internet nodes ftp.epa.gov or mountain.epa.gov The MMSOILS model system and selected other CEAM software products for microcomputer and/or UNIX installation and application can be down loaded through Internet from the above nodes via "anonymous" ftp (File Transfer Protocol) log in and file transfer commands and options. For further information on this Internet node and ftp, refer to document files USERINFO.TXT, QREF_WWW.TXT, QUICKREF.TXT, and LISTSERV.TXT that are included in the file INTERNET.ZIP that can be down loaded from the Internet node. To access CEAM software products via Internet, start the ftp program from the user's Internet node system (type 'ftp'), establish connection (type 'open ftp.epa.gov'), log onto public access server using anonymous account (type 'anonymous'). Respond to password prompt with users e-mail or Internet address. Then, upon log in completion, type 'cd epa_ceam', read CEAM Internet Welcome Screen, then type 'get CEAMNEWS.TXT -' to view latest news and list of CEAM software products available on the Internet. The same CEAM software products as mentioned above are also available through the World Wide Web (WWW). If the user has access to the World Wide Web, selected CEAM software products, including MMSOILS, can be accessed at the following Uniform Resource Locator (URL): http://www.epa.gov/CEAM _________________________________________________________________ DISCLAIMER Mention of trade names or use of commercial products does not constitute endorsement or recommendation for use by the United States Environmental Protection Agency. Execution of any portion of the MMSOILS model system, and modification to the DOS system configuration files (i.e., \CONFIG.SYS and \AUTOEXEC.BAT) must be used and/or made at the user's own risk. Neither the U.S. EPA nor the program author(s) can assume responsibility for model and/or program modification, content, output, interpretation, or usage. The MMSOILS program and files have been extensively tested and verified. However, as for all complex software products, the programs herein may not be completely free of errors and may not be applicable for all cases. In no event will the U.S. EPA be liable for direct, indirect, special, incidental, or consequential damages arising out of the use of the programs and/or associated documentation. CEAM software products are built using FORTRAN-77, assembler, other third and forth generation symbolic reference languages, and operating system interface command languages. The code structure and logic of these products is designed for single-user, single-tasking, non-LAN environment and operating platform for microcomputer installations (i.e., single user on dedicated system). NOTE: FORTRAN source code files are NOT required to document, execute, and/or test any model, program, or associated run time support file as provided on the distribution diskettes or the Internet installation file. MMSOILS is a large-scale complex model system. The model source code relies on multiple interdependencies. Modification and recompilation of FORTRAN source code files should be attempted only by experienced research personnel with substantial expertise in FORTRAN development tools and the MMSOILS modeling system. Their application is mostly for additional research and development, including comparison to field or laboratory data, other theories, and further enhancements, such as graphical interfaces. THE SEPARATE USE OF THE FORTRAN SOURCE CODE OUTSIDE THE MMSOILS SHELL IS NOT RECOMMENDED BY THE U.S. EPA FOR ROUTINE APPLICATIONS OR ENVIRONMENTAL IMPACT STATEMENTS. A user will be on their own if he/she attempts to install a CEAM product on a multi-user, multi-tasking, and/or LAN based system (i.e., Windows, DESQview, any LAN). CEAM cannot provide installation, operation, and/or general user support under any combination of these configurations. Instructions and conditions for proper installation and testing are provided with the product in a READ.ME file. While multiuser/multitasking/LAN installations could work, none of the CEAM products have been thoroughly tested under all possible conditions. CEAM can provide selected and/or limited scientific and/or application support for selected products if the user proves that a given product is installed and working correctly using the test input data files provided with the distribution release. o WordPerfect is a registered trademark of WordPerfect Corporation o Microway and Number Smasher are registered trademarks of Microway, Inc. o Intel, 386, 486, and 860 are registered trademarks of Intel Corporation. o F77L is a registered trademark of Lahey Computer Systems, Inc.
