I was a "railroad official" in the system administration group, meaning I was non-union, so I was not allowed to use a keyboard. Any program changes were made by writing on a coding form, submitting them to a keypunch operator, then submitting the cards in a deck to operations. The source files had eight-digit sequence numbers that were used for merging the patches. I had a text editor designed for interactive use against these same sequence-numbered files. I modified it to accept punched-card input, and greatly reduced the number of lines I had to put on the coding sheets. I could use replace and move statements, man that was technology at its finest! ;-) (Incidentally, the programmers were union members. Many of them had bid up from yard-clerk positions -- some of the most professional programmers I've worked with!) Vic
