This function sets a flag in the workspace that determines what happens when it is saved. The flag itself is part of the workspace and is saved with it.

If the flag is set, all Trace, Stop and Monitor settings will be cleared whenever the workspace is saved, whether by )SAVE, ⎕SAVE or by File/Save from the Session menubar.

Y must be 1 (set the flag) or 0 (clear the flag).

The result R is the previous value of the flag.

This function may be extended in the future and a left-argument may be added.
