Apparently you're saying you can only get the most
recent 'do', or did you do lots of stuff before
calling that function?
If you only 'do' one thing and it keeps returing a '1'
then i guess this method doesnt work.
As usual, MS implies that something like this WORKS because
if you read the doc's they say you can create a drop down
list of undo actions the user wants to do.
Sorry if it doesnt work.

Take care,
Al

And, good luck with your Euphoria programming!
