VRF-Repeat_Object_Problem

from Johannes Mulder, Philips Electron Optics
Just these days I am struggling with something like this (VEE3.12
under Windows):
I have problems with sequencing behind a UNTILL BREAK loop, and when
I step through my program, indeed the loop is not fired again. It
says 'Program terminated normally'. I don't have breaks in this
program.
With normal running it seems the program still runs, but it does not
react on user input, so maybe it thinks it is stopped.
