Re: experimenting with REGEX

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.

I am attempting to use a regex from rpg.
Ideally I want to create a regex to look for patterns of numbers, such as
9 consecutive numbers, or 999-99-9999, or 999 or 99999_9999 or 9999_99999
The separator can be anything.

To start testing I tried this (this was an example regex I found to look
for a phone number). I have plenty of phone numbers in the file.

scpattern = ' \b\d\d\d-\d\d\d\d' ;

rc = regcomp(reg:
%trimr(scPattern):
REG_BASIC+REG_ICASE+REG_NOSUB) ;

Read record

rc = regexec(reg:SCCOM:5:match:0)

if rc<> 0
callp regerror(rc: reg: %addr(buf): %size(buf))
scMsg = %str(%addr(buf))
else
except det
endif

then loop and read next record

All I ever get for RC is 1 on my regexec RC is 0 when on regcomp.

Any idea what I'm doing wrong?
Any idea how to make a regex for my scenario.?
