For anyone interested, the solution to my problem was:

ThisWorkbook.VBProject.VBComponents("mControl").Co deModule.Find("(Calculate|PrintOut)",
1, 1, -1, -1, True, , True)

This code will return True if "Calculate" OR "PrintOut" is found in
mControl module.

Hi Bob

Thanks for your reply. It appears to me that your suggested code is a
long-winded way of coding something that Excel VBA already automates.
The Find method has a PatternSearch argument. My problem is that I
don't know the syntax for the pattern search. I've been looking
elsewhere on MSDN (haven't got the answer yet) and I was hoping someone
here knew the syntax.
