GRCHAN 1.0 8.0 Graphics channel The desired channels may be given instead as an immediate argument in BINARY code to GROFF. Example: GROFF(13) will turn off Graphics channels 1, 3, and 4. If there is no immediate argument and GRCHAN is zero, all Graphics channels are turned off. ---------------------------------------------------------------- GROFF Type: Verb Use: Turn off (disable) one or more specified TV graphics channels. Does not affect status either on or off of channels not specified. Adverbs: GROFF takes an immediate argument specifying in BINARY code which channels to turn off. E.g. GROFF(43) disables graphics channels 1, 2, 4, and 6 (values 1 + 2 + 8 + 32 = 43). GRCHAN......Graphic channel. Only used if immediate argument is omitted. If the resulting channel number is zero, then all Graphics channels are disabled. Thus GROFF(0) and GROFF(255) are equivalent. ----------------------------------------------------------------
