This is hazy memory but I think Return worked like one would expect inside of multiline fields on those IBM terminals. That is, they used both Enter and Return, for different purposes. Also, if you're ever mystified by SQL's CHAR/VARCHAR handling of trailing whitespace, look into IBM "block-based" terminals and their text input and the conventions match exactly.
