Using DATA like arrays

[wallace]

I know why nothing is displayed on the screen, its these lines:

Code:

INPUT #1, a
         PSET font(i), (x, y), a

This will give you a black font, and you are probably writing on black right? Try this instead:

Code:

INPUT #1, a
       IF a THEN PSET font(i), (x, y), rgb(255,255,255)

That will make the font white. I'd explain the pointers, but the last posts seems to have done that fairly well.
