Re: [TUHS] 80 columns ...

The theory was that fixed size FORTH blocks with 64 (or 40) columns forced you to factor your code into aesthetically pleasing little functions, but that was bullshit. Forth code needs stack comments on every line to be readable, and 40 columns makes that damn hard to do. (Here’s some dense under-commented RPN 6502 and Forth code I wrote for my 40-column Apple ][ Forth — this does RAM card bank switching and copying for saving and restoring lines of text for the SUPDUP line saving protocol %TDSAV %TDRES commands.)
