The PS.DEV driver in the <Survo>\U\SYS directory defines all the control words available for printing and plotting on PostScript printers. Thus all control words in brackets (like [LANDSCAPE] for 90 degree rotation) are defined in the beginning of PS.DEV by using other control words or directly in PostScript code. At the end of this driver all the PostScript words and programs needed are listed. You can view this driver by SHOW <Survo>\U\SYS\PS.DEV or print it on paper (provided that your Survo installation includes the PostScript option) by 11 *PRINT 12,13 12 - [Courier(8)][line_spacing(8)] 13 - text <Survo>\U\SYS\PS.DEV Supplementary PostScript drivers (to be used in connection with PS.DEV) are GCHAR.DV2 for graphic characters (drawing boxes around the text), MATH.DV2 for mathematical symbols, PSFONTS.DV2 for additional PostScript fonts.
