If you consider what '0 or more occurrences' means, in the context of looking for [A-Z]{1} followed by '0 or more occurrences' of [0-9], that's really no different than looking for [A-Z]*; after all, '0 or more occurrences' means you don't really care whether there are any of [0-9] after [A-Z].

Maybe I should have put it more clearly.

I want to find

C
C1
C2

but not

CA

If Find What: [A-Z]*
it returns C, C1, C2 and CA (which is not wanted).
