IntyBASIC Graphics Un-Define?

[First Spear]

I am having a brain freeze here. I need to zero-out (replace with $0000) some GRAM blocks that were previously defined. What is the most efficient way to do that? Sometimes it's 3-5, sometimes it is GRAM 60-63, etc. Arbitrary GRAM location ranges.

 

Thanks.

This might sound dumb, but the most straightforward way to do this is probably:

' Four zeros for each card, up to the max number of cards you want to clear.
ZEROS:  DATA 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

...

DEFINE card_num, count, ZEROS

It's inelegant, but it should work.

 

AFAICT, the card_num and count aren't required to be compile-time constants.
