| Description |
a term used to describe the ability to interrupt a process, invoke a "new" TCL prompt, and execute any valid TCL command.
If a <return> is issued at the "new" level TCL prompt, control returns to the previous level, exactly where it left off. It is possible to "logto" another account while at a "pushed" level. When a <return> is issued at the TCL prompt, the process automatically returns to the original account. Any tape or peripheral storage devices attached to the process when logging to another account at another level remain attached in the new account. |

| Warnings |
Processes in suspension (i.e. "pushed" processes) may have items "locked", which can stay locked forever until the level is re-entered. The same thing may happen with tape devices.
A Unix process submitted from Pick is cancelled if a level-pushing key is pressed while it is running. |
