We had dedicated ttys with APL keys. Program development was adding one symbol at a time, trying what happened. Repeat until the program was finished. For real programming we wrote Algol on punch tapes, later punch cards. Turnaround time was one day, so you wrote the program, printed it, checked manually, proved its correctness (I was educated by EWD) and then delivered it at the computer department. APL wouldn't have stand a chance in that environment. I did like the language, in a peculiar way. -- Johan _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
