Complex Lock mode for WP-34s

[Paul Dale]

There are flags for checking if a program is executing: Running & XromRunning.
Having ENTER do what it normally does while either is set should work.

I think we'd be better off with a new branch for this -- like for the 31S and complex mode. There is enough mess in the main code already and as time progresses, all of us remember it less well.
