Well, if you were a serious programmer, major segments of code came in the drawer of a card filing cabinet (I don't recall exactly, but I believe one held about two boxes.) However, then the idea was to get them onto tape before something dreadful happened, such as being subjected to a jam or being rejected because of a compare error in the reader. I can recall on more than one occasion where an I/O clerk with a cart loaded down with card trays hit a loose trim strip in a raised floor. Mayhem indeed. If you were smart, you drew a long diagonal across the top of the card deck with a felt-tip pen to at least give you some sort of clue about the order. There were SCCS type of systems even back then. SCOPE had UPDATE, which corresponded to KRONOS MODIFY. Each card was assigned a set identifier and sequence number, used as reference when editing. Updates could be YANKed or PURGEd as necessary. --Chuck
