HELP SECTION

GRON
Type: verb
Use:  Turn on (enable) one or more specified TV graphics channels .
      Does not affect status either on or off of channels not
      specified.

      Note that, if GRON is used in a FOR or WHILE loop or in an
      IF-THEN-ELSE construct, then the immediate argument is required.
      Otherwise, some item necessary to the loop/construct will be
      taken as the immediate argument.

Adverbs: GRON takes an immediate arguement specifiying in BINARY code
         which channels to turn on.  E.g. GRON(43) enables graphics
      channels 1, 2, 4, and 6 (values 1 + 2 + 8 + 32 = 43).

  GRCHAN......Graphic(s) channel.  Only used if immediate argument is
              omitted.  If the resulting channel number is 0, nothing
              is done.
