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 MULTIMED 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 MULTIMED 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 MULTIMED model system. Introduction ~~~~~~~~~~~~ Complete the installation process to make the full or any portion of the MULTIMED 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 of the MULTIMED model system. DOS Storage Path ~~~~~~~~~~~~~~~~ Verify that the MULTIMED model system executable task image files (*.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 MULTIMED installation sub-directory (e.g., C:\MULTIMED) 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:\MULTIMED If any portion of the MULTIMED 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 MULTIMED model system installation sub-directory to the current default sub- directory from where the MULTIMED 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 MULTIMED 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., MULTIMED). Use the DOS CD (change directory) command at the DOS system prompt: C:\> CD \MULTIMED ------------ 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 PREMED program, type: C:\MULTIMED> PREMED ------ Follow the menu and parameter options presented on the display screen. Execution of this program is optional. However, prior to its execution, the MULTIMED model requires an input data file that has been built either with the PREMED program or manually using a word processor or text editor that can save a file in ASCII text (non-binary) format. 4) To execute the MULTIMED model, type: C:\MULTIMED> MULTIMED -------- After an opening banner/registration screen is displayed on the monitor, press the key to clear the screen, then select from and follow the information screens and prompts displayed on the monitor screen. 5) To execute the POSTMED program, type: C:\MULTIMED> POSTMED ------- Follow the menu and parameter options presented on the display screen. Execution of this program is optional. However, prior to its execution, this program requires a plot data file that has been built either with (1) the MULTIMED model, or (2) manually using a word processor or text editor that can save a file in ASCII text (non-binary) format. Viewing Output Results ~~~~~~~~~~~~~~~~~~~~~~ After executing a MULTIMED model system executable task image file, the user can view an output file, 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 files that exceed 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 MULTIMED 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 MULTIMED model system will be processed and executed in that run of the program or model. 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). Any DOS file name can be from 1 to 8 characters and can have an optional 1 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 files furnished with the distribution version of the MULTIMED 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 MULTIMED 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 512K byte cache SCSI controller, a 256K byte memory cache, a 50 megahertz clock, a Number Smasher-860 40 megahertz, 32 megabyte math numerical coprocessor, and an ATI Ultra Graphics 1 megabyte video card. ** MULTIMED Model System Test Runs Input Data File Name Approx.
