Paul,
The difference lies -I think- in the "Basic" vs "Extended" form of
regular expressions.
See also p.e.
http://en.wikipedia.org/wiki/Regular_expression
On the regcomp, use REG_BASIC (or REG_ICASE )
Or use REG_EXTENDED (REG_ICASEX) with the full [A-Za-z0-9] notation.
Kind Regards

subject: Regular expressions - which taste ?
Hi,
Using the C functions for regular expressions in RPG, I noticed that
only some of the expressions work.
For example the \w and \s seems to compile fine, but it always fails on
the actual compare ?
I expected that patterns as described on
http://publib.boulder.ibm.com/infocenter/systems/topic/rzaie/rzaieregexp
not.htm would work, but this doesn?t seem to be the case (or am I doing
something wrong) ?
Are there different regular expression dialects, and which one is being
used in the C functions ?
Kind regards,
Paul
