RPG is/was a programming language that grew out of a text processing application. It invovles column-specific commands (i.e. if col. 47 contains a "3", then do this... (as defined by the language).
CSound does this also. (CSound is sort of a pseudo-coding environment which outputs sound-files instead of executables. It's open-source, written in C, so if there's anything you want it to do that it doesn't do already, you can add that functionality and recompile it yourself. I'm pretty sure I've talked about it a bit on-list before.)
Actually, to be a bit more accurate... CSound *sometimes* involves column-specific commands, but it usually counts columns after the end of a specific keyword. For example, "f" followed by a number (i.e. "f3" or "f275") starts a line that defines a function table, and the first 4 columns after the end of the number are standard commands and columns after that do different things depending on the "gen" routine (sound generating table reading routine) that calls for that particular table.
