Chas,

Thanks. I will run off to that man page.

I am considering that change the next time around. It certainly simplifies the
area where I am trying to perform the main match. It does however introduce a
little confusion for a newbie such as myself haveing a variable contain a
variable sort of thing.

The challenge that I am working on now is that although the $RE{num}{real}
simplifies the match of real numbers it does not appear to help me with
fractions. i.e. 36 1/2' Sighhhhh. I looked through Regexp::Common::number and
didn't see anything that pattern matched fractions. A search turned up
Number::Fraction but that doesn't seem to be about pattern matching.

I guess I will try to roll my own using the qr operator. A learning day! ;-)

Thanks for all your help.

Kind Regards,
Keith
