I remember punch cards, keep the JCL cards and throw everything else away when the program was done. They were into flow charting too, remember seeing the plastic templates. Remember when I had to take Cobol and PL/1, PL/J. Had to get to the computer room early so I could get a punchcard machine. Was so happy when I got a Wylbur account so I could use a terminal. The good terminals were in the front and you had to get in early for those. During winter, the crap terminals were static electricity sensitive, touch them the wrong way and the cursor would jump up the screen. Can end up with an unprintable char in your code and that would mess up the printout and maybe the code may not run. Don't think about deleting the char because the cursor would jump away.
