APPENDIX A – Computer Setup A1 Hardware Requirements Desktop computer: The programs are written for a PC-compatible computer (with math-coprocessor, on 386 or equivalent, or older, PCs) running DOS (version 3.3 or higher). You must have 5MB available on your C: drive to be able to install the program (plus another 400kB or so if you want LApp, the Los Alamos polycrystal plasticity simulation code, on any drive). A few of the programs (e.g., OWIMV, LApp) can be used only if you have a 386 or higher, with at least 4MB of extended memory, running under DOS 5 or higher. Monitor: This is critical only for our Polar Orientation Density (POD) program. It is written specifically for the VGA, with standard resolutions (480x640). You will need a minimum of 8 colors of gray shades, which works best on a 256-color monitor! Laptops with 8 or 16 “true gray shades” should first be tested. Hardcopier: A Hewlett-Packard Laserjet Series II or higher with an extra 1MB memory board is extremely desirable. Again, this is most critical for the POD program: all our area-fill graphics is written with a downloadable font for the Laserjet, and it works very fast. We also give you the option to produce a PostScript file, which you may use on other printers; it is slow. All the curve-plotting we do uses commercial drivers designed for the Laserjet (and some HP plotters, with possible conversion to the Laserjet). A2 Software Requirements The way your PC responds is governed by two files, in the versions that are active when you (re-)boot: CONFIG.SYS and AUTOEXEC.BAT. Memory and CONFIG.SYS Some of the programs need 540kB usable RAM. If you run CHKDSK, the last number tells you how much “free memory” you have. If it is not enough, eliminate unnecessary instructions from your CONFIG.SYS (such as the shell). For this reason, some programs will not run in the DOS window of WINDOWS. Also, you may have to make sure that nothing is running in the background, such as a terminal emulator or the Norton Commander. We do not use a mouse. The CONFIG.SYS file must contain sufficient BUFFERS for the menu to run fast. It also should contain, if possible, at least a memory manager that keeps as much as possible out of "lower memory" (the 640 KB RAM). The programs labeled "386" (including LApp) need an extended memory manager that is compatible with Lahey's executable files. If all else fails, install merely DEVICE=C:\DOS\HIMEM.SYS DOS=HIGH,UMB in CONFIG.SYS and reboot, for the time you need to use these programs. It is very handy to have a print spooler. There are various commercial products that need installation either in CONFIG.SYS or in AUTOEXEC.BAT. Paths and AUTOEXEC.BAT Any AUTOEXEC.BAT file already contains a PATH statement. It must be augmented by ;C:\X This allows for executable popLA files (ending on .EXE or .BAT) that are stored on C:\X to be used from any (sub)directory on any drive. A difficult question is the use of "appended paths". We used to recommend that you use one, by inserting the line, in AUTOEXEC.BAT, after the PATH: APPEND C:\X /path:on This allows even non-executable popLA files (such as those ending on .SYM or .WTS, etc., or those having no extension, such as PODIN), which are stored in C:\X, to be used from anywhere. However, some newer DOS programs as well as Windows may misbehave, and it is currently recommended by Microsoft to delete all APPEND statements. Two alternatives exist. One is to copy all the non-executable files you need for a particular project from C:\X into your current subdirectory. In particular, this must be done when some of John Kallend’s properties calculations on p.7 are used. The other option is to explicitly state the full path name in answer to any query for a file. All the common filenames should now have been dimensioned long enough, within the programs, to allow for this procedure. It is the first recourse when a programs says, “Can’t find that file”, or something to that effect. (Note that data file names are restricted to 12 characters: you must work in your data directory.) APPENDICES 36
Screendump For the best reproductions, you need a program to convert the screen image to a .PCX (or other binary) file: all is prepared for you to use one. (We use GRAFLASR.) Then you can make hardcopies on a color printer or via WINDOWS PAINTBRUSH. Also the Polaroid C-5000 is very handy (though slow); we use it both to make (small) color transparencies or slides and to produce negatives for publishable black/white prints. Finally, you can convert a .PCX file to a Macintosh .PICT file and do further editing by a program such as CANVAS. A3 Program Installation The whole program structure assumes that all executable files, and some others, are located in a directory C:\X. If you have such a directory now, save the contents somewhere else; if you don’t have one, you don’t need to create it. Insert the “yellow” popLA disk in your floppy drive, make it your default drive, and type INSTALL. The installation procedure does not lead to copying all of the “blue” disk. You may wish to type XSOURCE to unpack the source codes for some of the input/output and massaging programs of the texture analysis package, to facilitate your adaptation to different schemes or tastes. They should be compiled with MSFORT (some need version 5 or higher). A batch file MSF.BAT is included with the right options spelled out. You would also need the libraries supplied (plus those for the compiler). In addition, from the “yellow” disk, subdirectory \386, you may unpack XLAPP for our Los Alamos polycrystal plasticity simulation code, preferably into its own directory (e.g., c:\LApp) This is a research code that will continue to evolve. Some instructions are given at the end of this manual; however, you would have to cooperate with Fred Kocks or Tony Rollett to use it in more than a cursory manner. You may have to modify POPLA.BAT (the main menu file)to adjust for you particular system. For example some do not recognize the @ at the beginning of lines to suppress their printing, resulting in much garbage appearing on the screen. Or you may not have some handy utilities such as LIST.COM (replace LIST in line 78 of POPLA.BAT by BROWSE or whatever), D.COM and DDIR.COM (replace by DIR). You may also write your own batch file, for example to contain only your standard options. Use POPLA.BAT as a guide. You absolutely must have your data in ASCII format. Then you have to convert “their” format to ours (see Appendix B2). For SCINTAG’s, PHILIPS’, RIGAKU’s and Aachen’s standard files, we have included conversion programs (both source codes and compiled): you get them into your current directory by typing A:\XCONVERT (replacing the A by whatever drive you have inserted the “blue” disk in). A4 Some Features of DOS DOS is a Disk Operating System based on a command line interface: the computer is controlled by typing short commands with various parameters and hitting the Return key at the end of the line to tell the computer to process the command. DOS tells you that it is ready to process commands by printing a prompt. A typical MS-DOS prompt is C:> The first character is a letter, usually A through D. It refers to the drive currently in use. For historical reasons, the floppy drives are known as A and B and the larger hard disk is known as C:. Higher letters are usually additional drives, obtained by partitioning the hard disk. To change from one drive to another, type the name of the drive followed by a colon. To organize files better, each drive is separated into directories and subdirectories. DOS keeps track of the current subdirectory that you are in. You can change to another directory with the cd command,; e.g.: C:> cd X The response will be a prompt C:\X> (If it is not, insert a line prompt $p$pg in your AUTOEXEC.BAT file.) To make a new directory, for your texture data and analysis files, as a subdirectory of C:\X, type (while you are in C:\X,) md texfiles Other DOS commands you will need are (by example): copy a:\tex1.dat c:X\texfiles\cu0.111 ren(ame) diorout cu0.SWD del(ete) *.BAK The last one deletes all files ending on .BAK APPENDICES 37
