overflow when using poke

[shanley06]

when i use

poke varptr(vscreen%(0))+(320*320)+200,15

it gives me an overflow error, i was wondering if there was a way around this or a way to fix it

This is the code you want to use

DEF SEG = VARPTR(screen%(0))
POKE (320 * 320) + 200, 15
DEF SEG

The address of the POKE can only be between 0 and 65535, so you have to change the segment address to go any higher

^^^^^ Don't use ^^^^^

never mind - i did that completely wrong, I must not have gotten enough sleep or something. I looked at your other post and you did use DEF SEG.
The reason you are getting the error is because (320 * 320) + 200 = 102600, which is must higher that 65535. You have to change your segment address again.

how can i tell waht to change the segment to if the offset is too high?
