That way, legacy code is guaranteed to always run in four-level mode, regardless of the user's preferred interactive mode. And it is always obvious at a glance which mode any given program will run in.

Thomas,
IMHO this is the best route to take, I was going to suggest the same idea until I saw this post.
It's simple, the intention is clear and the compatibility with older program is guaranteed.
There are cases that will need to be addressed like: { LBL "L1" ... XEQ "L2" ... RTN } { NLBL "L2" ... RTN } or { NLBL "L3" ... XEQ "L4" ... RTN } { LBL "L4" ... RTN }
