1 Getting Started

TO RUN Puff, you need an IBM PC, AT, PS/2 or compatible, a graphics card and display, and DOS 3.0 or later. For best performance we recommend a computer with 640 kilobytes of memory, a math-coprocessor chip, and a hard disk. Limited operation is possible with less memory, and floating point emulation is used if no coprocessor is present. The program works best with a Video Graphics Array ( VGA) display and adapter. All the screens shown in this manual use the VGA. The smaller text in the VGA mode makes room for more characters, allowing an extra decimal point of numerical precision to be displayed. Puff will also work with the Color Graphics Adapter ( CGA) and the Enhanced Graphics Adapter ( EGA), but the screens will appear different than shown here and some of the numbers displayed will lack the extra decimal. In order to make a hard copy, you will need a screen-dump routine for your display and printer. The following programs have been included on your Puff diskette:

These are stand-alone programs for doing EGA and VGA screen dumps on Epson, IBM Proprinters, and HP LaserJet printers, respectively. Use them in the same...
