[from the operation that puts the current information on a stack, and the fact that procedure return addresses are saved on a stack]
Also PUSH /push/ or PUSHJ /push'J/ (the latter based on the PDP-10 procedure call instruction).
1. To put something onto a stack or pdl. If one says that something has been pushed onto one's stack, it means that the Damoclean list of things hanging over ones's head has grown longer and heavier yet. This may also imply that one will deal with it *before* other pending items; otherwise one might say that the thing was 'added to my queue'.
