green card
n. [after the IBM System/360 Reference Data card] A summary of an assembly
language, even if the color is not green and not a card. Less frequently
used now because of the decrease in the use of assembly language. I'll go
get my green card so I can check the addressing mode for that instruction.
The original green card became a yellow card when the System/370 was
introduced, and later a yellow booklet. In fall 2000 it was reported from
Electronic Data Systems that the green card for 370 machines has been a
blue-green booklet since 1989.
