Palette Control ID
The Palette Control ID command specifies the ID number to be used
by the Palette Control Command.
?&p#I
The ID number specified by this command is saved as the palette
control ID in the current modified print environment and is used by the
Palette Control command (
?&p#C).
?E or power-up resets the palette control ID to 0, which is then the
default black and white palette ID.
Macros affect the palette control ID value as follows:
Calling a macro—saves the value and restores the value at
exit.
Executing a macro—does not save the value; changes remain
in effect at exit.
Overlaying a macro—copies the value before resetting to 0,
and restores at exit.
