    It's *Backward-compatible-Man* ("BM"), to the rescue!

    The other response you got for system 8.5 and above- I guess that's
the right way to do it, though it seems like alot of trouble for what
you want to do.  For earlier OS, you might try something more brute force:

    The PPob file you're editing in Constructor- if you drop that file
on ResEdit, you'll notice the 'WIND' resources in there which correspond
to your LWindows- the LWindow will be using that regular ol' Mac
toolbox WIND resource to *base itself* on- the values in that WIND are
used in creating the LWindow.

    So, you've almost answered your own question- just grab that WIND,
change the field with that position value, before you execute the
code which causes UReanimator to read that PPob, which contains an
LWindow, which reads that WIND.  See?

Handle  windH   = ::Get1Resource( 'WIND' , theID );
HLock( windH );
(*windH)[ theOffset ] = centerMainScreen;
HUnlock( windH );
NowDoPowerPlantCodeToLoadAndShowWin( theID );

    As far as theOffset, *where* that value is stored, I think it's
the last two bytes of a system 7 or beyond WIND, but you can deduce
it for yourself either by playing in ResEdit, ( duplicate the WIND,
alter the "autoPosition" of one from the menu, compare those two ), or
add up what you see in "MacWindows.r" describing the WIND.  See?

    Who *was* that BitMasked man?
