Re: experimenting with REGEX

[Billy Rowe <billyrowe@xxxxxxx>]

I believe the reason Mike is getting an error is because the regex 
engine used by the iSys utilities
is the POSIX BRE and POSIX ERE engines which don't allow the word 
boundary designation "\b".

This regex should work as a POSIX ERE and find North American phone numbers:
\(?[0-9]{3}\)?[-. ]?[0-9]{3}[-. ]?[0-9]{4}

It can be modified for other number patterns desired.
