Why not put this in a "repeat forever" loop and test for iStopp=0, then exit
repeat when true?
Put 1 into iStopp
Repeat while iStopp<>0
Intersect testing code that puts 0 into iStopp, appropriately
If iStopp=0 then
Exit repeat
End if
End repeat
Of course, there is probably some reason, but this is the way I would probably
approach this.
