"One day I was programming and I tried to make a variable called COMBAT [on the Atari]. I got an error and after a little deduction I found a command called COM which has something to do with DIMensioning variables, but there is no explanation of it in the Manual. Does anyone know what COM is?" Jeffrey Naiman

COM is, as far as we know, identical to DIM. DIM A$ (30) is the same as COM A$ (30) We do not know why Atari BASIC contains this "extra."
