Have been unable to find any help on these details, nor any VB programmers
who can give a definitive answer...

the subject line code is default for many event subs in VBA. exactly what is
setting the Cancel var?? to put it another way, when or what would cause the
var Cancel to be True? Have tested in a huge # of scenarios involving closing
and cancelling forms and controls, and have yet to see Cancel = anything
besides False.

also...ReturnBoolean is obviously not same as Boolean. can it be anything
else besides True or False? would it be useful anywhere else?

thanks for any replies :)
