Graphics Demo bug

Not sure if this clobbers anything important but:

VAR
....
long colors[noparse][[/noparse]64]

'init colors
repeat i from 0 to 64
colors := $00001010 * (i+4) & $F + $2B060C02

should be:

'init colors
repeat i from 0 to 63
colors := $00001010 * (i+4) & $F + $2B060C02

Is there someone we should be PM'ing or e-mailing these kinds of things to?

Thanks,
Kerry

The 'init colors with i=64 doesn't matter because,
it is only done once at the program start and then after 'init tile screen
'init bouncing lines uses the long properly for
byte x[noparse][[/noparse]lines]
byte y[noparse][[/noparse]lines]
byte xs[noparse][[/noparse]lines]
byte ys[noparse][[/noparse]lines]
this is ok only because "long colors[noparse][[/noparse]64]" occurs immediately before to them in the VAR declarations.

I am assuming that there is no other programing that uses color data beond 0 to 63.

Woops! You're right. I just fixed this and will re-post it along with the other objects once our object exchange is running. I don't think it's up yet, but we've got a new web thing coming where everybody can upload and maintain their objects on their own. It's going to be really nice.

Thanks for pointing this bug out.
