I~ <br />i <br /> <br />IMRODUCTION TO HVDROCALC HYDRAULICS <br />HYDROCALC HYDRAWCS MANUAL. PAGE 9 <br />1) Before starting the HYDROCALC° Hydrauliq program, type the word GRAPHICS. The GRA- <br />PHICS.COM file which was supplied on your DOS disk must be present on the current disk <br />in your computer for this command to work properly. This command can be p,~ven in the <br />AUTOEXEC.BAT ille, so that tt will be executed automatically each time you start your <br />computer. Your DOS manual describes the purpose of the AUTOEXEC.BAT file. <br />2) Start one of the HYDROCALC° Hydraulics programs and use the program to display a graph on <br />the screen. <br />3) Make sure that your printer is properly connected to the computer, plugged in and turned on. <br />Remember -your printer has to be compatible with the graphics printers listed >n your DOS <br />manual. <br />4) While the graph is displayed on the computer screen, press "Shift-PrtSc" (press the a=s ~= so=n <br />key wh11e holding down the Shift key). Your printer should begin to print the contents of the <br />screen. The graph will be displayed sideways. Three or four minutes may be required for <br />printing to be completed. <br />If a screen graphics dump utility was supplied with your printer or 1s avallable sepazately for your <br />printer, you may be able to use this utility in place of the DOS GRAPHICS.COM f31e to obtain <br />printed graphs, even though your printer may not be compatible with the Epson printing routines <br />bu11t into the HYDROCALC° Hydrauliq programs. <br />1.8 PROGRAMMING NOTES <br />This program 1s written using the "llsbo Pascal 3.0"complier from Borland International in Scotts <br />Valley, Ca. Parts of "Procedures and Functions for'h~rbo Pascal" by William Todd of The Success <br />Press in Des Plaines, Ill. are incorporated into the program. Additional guidance for programming <br />was gained from Peter Norton s book "Inside the IBM PC", published by the Robert J. Brady co., <br />Bowie. Md. <br />The programs were developed on a Compaq 286 portable, an IBM PC AT, and a Compaq Plus <br />portable computer, using Ashton-Tate's powerful "~Yamework" integrated software program to <br />outline and edit the source code text and the program manual. The manual 1s printed using the <br />Lotus Manuscript document preparation system and an NEC Sllentwriter PostScript page printer. <br />Some of the graphics routines are derived from the excellent "llirbo Pascal Science and Engineering <br />Tools" by guirm-Curtis, 7 Fredette Rnad, Newton Centre, MA 02159. The Epson printer interface <br />and the routine to detect the presence of the correct graphics board are derived from Borland <br />International's "Ilu~bo Graphic Toolbox". The Hercules Monochrome Graphics Card routines are <br />adapted from public-domain procedures written by Jon Rifkin, 196 Ference Rd., Stafford Springs <br />CT 06076, which were obtained via CompuServe's Borland Special Interest Group. <br />The Pascal StruMure Analyzer (PSA) program has been used to analyze the source code and <br />eliminate some types of programrntng errors. The PSA program 1s supplied as a part of the Tur- <br />boPower Utilities package from TurboPower Software. <br />These programs are supplied in executable form only. The source code is not available. However, <br />suggestions for changes to the programs are welcome. <br />O 1989 Dodson & Associates. Inc.. 5629 FM 1960 West. Sulie 314, Houston. Texas 77069.
