Threaded Mode | Linear Mode

When debugging a program with LNSTK, executing RTN from the keyboard does not return to 4STK mode.

Yes. Executing RTN from the keyboard deletes all local variables and restores the IJ pointers if the indexed matrix was hidden by a local variable, but it does not undo the effects of FUNC, L4STK, or LNSTK. I think doing so would get messy, and produce surprising results when the user doesn't expect it...

I would argue that the ones using those functions know what they are doing ;-)
After all, your local variables will disappear as well, why not your local dynamic stack?
I agree that FUNC should NOT be taken into account when executing a manual RTN, though.

I could make it restore the stack mode, but without restoring the stack contents... I considered that possibility while implementing LNSTK and L4STK, but I don't remember why I didn't go ahead and do it. It seems like a pretty reasonable thing to do.

I made the change. It will be in the next release of Free42 and the next test build of Plus42.

Thanks, Thomas!
