I would keep it. Not as a DO terminator (always use END DO), but I find it a useful place to "hang" labels for the few GOTOs (or end= or err=). In fact my personal style is to never GOTO anything except a CONTINUE. No real point in enforcing that style preference, but I think its one that should be allowed. Putting a GOTO target label on an executable statement can complicate maintenance when you discover that you want to add something before the currently labelled statement. > Remove spacing control for line printers. Yes. I'm enthusiastically in favor of removing that from the subset. It causes no end of complaints and compatability problems (different systems doing the carriage control in different contexts). I've personally adopted the practice of always putting blank carriage control characters on every line meant for output to the terminal. I never use any other carriage control character. (If I want to skip a line, I just write a blank line). This way, things work ok regardless of whether the carriage control convention is applied or not - just means that everything is shifted one space to the right in some/many cases, so I need to be sure to stop at least 1 character short of the maximum expected terminal width. This is the only way I've found to be very portable, and it seems sort of silly. In fact, I'd also be in favor of adding a CARRIAGECONTROL="NONE" (or some other spelling of the same concept) option to the full language. -- Richard Maine maine@altair.dfrc.nasa.gov
