Also, the user <br />will be prompted to input a name for the Postscript file, with the suffix BPS automatically <br />appended to the filename. It makes use of the routines rasttoppm, ppmtopgm, and pgm- <br />toeps.Finally, the user can send a portion of the screen directly to the printer by using the <br />right mouse button. This uses the script files printerstuff/PSPRT or printerstuff/ <br />PSPRTSCALE, again ifre-scaling is necessary. It makes use of the routines rasttoppm, <br />ppmtopgm, and pgmtops.All of these files must reflect the local computer/printer configu- <br />ration. These files need to be consistent with the computer/printer configuration that the <br />24MSI is running on. Specifically, at the end of each script is the command to pipe the <br />output to the line printer (j lpr -Pps). The flag on the lpr command, .pps, must be updated <br />to be the name of the desired printer. <br /> <br />1.11 Source Code Documentation <br /> <br />Descriptions of the source code routines can be retreived online. This is acheived by typ- <br />ing "man <routine name>" (e.g. man blegend), which emulates the UNIX online ability to <br />access a description of a command. The description consists of the subroutine/function <br />name, its parameters, the authors and editors, the variable names and descriptions, com- <br />mon blocks, and external function declarations. <br /> <br />The online documentation of the routines described above contains the items in the head- <br />er of the actual source code for the 24MSI routines. This information is gotten by strip- <br />ping the header information directly from the source code. To do this, a program was <br />written to check each line to see whether or not that information should be included in the <br />header/man page. This program, reference, is located in the directory headers. If the <br />source file of a routine is changed at any time, this program must be run on the source file <br />to create an up-to-date version of the *.p file (simply the stripped header of the source <br />code). This is done by the command "headersfreference <filename>! headersfpdirecto- <br />ry". Then the resultant file, that is the <filename>.p file in the pdirectory must be moved to <br />the directory where all of the stripped header files are located. These header files need to <br />be located in the fusrfmanfmanp directory. <br /> <br />24 Month Sludv Proiect :Doa.lmenlalion Volume n <br /> <br />618/91 <br /> <br />10 <br />
