should be a tad faster...12Me21Head AdminThird YearMy account is over 3 years oldWebsiteSyntax HighlighterReceived for creating the code syntax highlighter on SBSNight PersonI like the quiet night and sleep late.Express YourselfYes, but be careful, because the types of the input variables depend on the value that is passed to them (type suffixes don't actually do anything there):

Anyway there are a few minor mistakes:
- FOR I=0 TO H should be FOR I=0 TO W-1
- F = ABS(N-1) can be F = 1-N (Results are the same, but it's simpler)
- Y+H and X+W should be Y+H-1 and X+H-1
And you should make this into a function:
DEF GRADIENT X,Y,W,H,C1,C2,VERTICAL

RGBREAD C1 OUT R1,G1,B1
