A coding sheet designed by IBM for the IBM System/360 Assembler. The card provides space for up to 80 columns of characters to be filled in by the programmer, each containing an IBM System/360 Assembly statement and an identification sequence number. Each line of the form’s table represents a punched card that would be produced from this coding sheet, with space for 24 rows of instructions to be punched from each sheet.
The sheet forms a pad with approximately 100 identical coding sheets remaining. Originally, pads of several hundred sheets would have been issued to programmers which could be filled out, peeled off the pad and submitted to a keypunch operator to be punched onto IBM 80-column punched cards. These could then later be processed by an IBM System/360 to execute the new program.
