Limitation of QAB Zoom facility - A4000003 - 18 Nov 1999
We recently heard of a problem that some users have experienced with PROGMAKE
due to a misunderstanding about how the Zoom facility is intended to work.
Users were zooming in on a procedure, then changing the procedure at the top of
the zoomed tree to a different procedure (and possibly doing further editing).
When they exited PROGMAKE they were surprised to discover that the original
procedure was still in place, and that their changes were lost. The explanation
of this behaviour is as follows:
When you use the Zoom facility of QAB to focus on part of the procedure tree,
you are editing a new temporary procedure tree, so changing the top procedure
to a different procedure will not replace the procedure in the actual QAB
program. If you want to replace one procedure with another and need to use
zoom to get at the procedure, then remember to zoom in on the procedure above
the procedure you want to replace and not the procedure itself.
