Does anyone remember Basic-4 systems? I transferred several programs, in those days and on that system with a maximum of six characters for the name, from one machine to another via magtape. One was named "CR" (customer report or credit report, who knows). It disappeared on the new system because it was mistaken for the Card Reader.
