Programmatically changing Entry mode crashes iOS Pro App

[pinkman]

Thanks Cyrille.
Yes I had this in mind. I did not know the RETURN -1 option, my code tried to return nothing, but this does not really exist in HPPL.

The issue is clear for me:
- changing view drives to lose what I would call the calling context: it is not a bug,
- not handling such cases when returning from a program: this is the bug.

Now I’m wondering why the crash occurred randomly...
