Hi Al,

thanks for the advice; 
but I don't refer to the absolute POSSIBLE number of these steps 
(the LIMIT is 100, with the win32lib 0-59), but the current stack counter, 
i.e. how many Undo commands can be executed, or the true number of changes 
that culd be undone in any moment.

Somebody else?
