Hi,
After seeing Larry Virden's message I checked my previous answer. It
looks like regexp was enhanced post tcl8.0 which is what I'm still
running. Larry's test script didn't give expected results on 8.0,
but of course did on 8.2.
Just thought I'd mention this in case backward compatibility is an
issue.
