HELP SECTION

DEFCOLOR
Type: Procedure
Use: DEFCOLOR sets the LWPLA adverbs DOCOLOR to 1 and PLCOLORS to
     those colors that a task would use when DOTV=1 with a default XAS
     TV display.  This procedure works whether or not you have a TV
     running.  It sets PLCOLORS to
        PLCOLORS = 1,1,0, 0.063,1,0, 1,.671,1, 0,1,1
        PLCOLORS(1,9) ~ 1,1,0
        PLCOLORS(1,10) ~ 0.02, 0.02, 0.02
     LWPLA now changes pure black (0, 0, 0) to white forcing this
     last one to be not quite 0.
Output adverbs:
  DOCOLOR.....Set to 1.0 to tell LWPLA to use PLCOLORS.
  PLCOLORS....Line types 1-4 get colors yellow, green, pink, and cyan.
              Types 5-8 ("dark" vectors) are black, Type 9 (labeling)
              is yellow, and the background is black.
