Thanks. That is a smidge more compact. Although it doesn't quite jump off the page w.r.t. readability. <BR>
<BR>
I was hoping for something along the lines of Progress: <BR>
Table = entry(1, FullName, "."). <BR>
<BR>
But I shall take a look at BASH_REMATCH. <BR>

Yes there is. You specifically said "bash" in the subject and in the
talks we've had a ALE and AUUG over "belts and suspenders bash" the
speaker mentioned using regex's in bash and accessing the underlying
substring results. Look for BASH_REMATCH variables and the =~ operator
in the bash documentation.
--
FOO=CustomerEntry.CreditLimit
if [[ "${FOO}" =~ (.*)\.(.*) ]] ; then
echo "${BASH_REMATCH[1]} : ${BASH_REMATCH[2]}"
else
echo nope
fi
CustomerEntry : CreditLimit

Is that what you're after?
