Re: iSphere Source File search - regular expressions

Can anyone point me at the right page for the regular expressions engine
used by iSphere (the iSphere help says "IBM regular expression functions"
which doesn't help me). I can only find Java and GNU regular expression
details in google searches.

I poked through the Java, and it looks like it runs RPG code on the IBM
side in a service program called FNDSTR. That code uses the C library
functions:
regcomp()
regexec()
regerror()
regfree()

The documentation in the 7.3 Knowledge Center is sparse, saying only
this: 'The functions regcomp(), regerror(), regexec(), and regfree() use
regular expressions in a similar way to the UNIX awk, ed, grep, and
egrep commands.'

Pretty sure that this is the Posix-awk variant, not GNU.

I'm trying to find a hard-coded value of 91 in my source. "\b91\b" works
fine in LPEX's find tool in each source member I look in, but iSphere's
tool doesn't bring any results at all using that regex.

I'm dealing with RDi v9.5.1.2 and iSphere v3.0.0.r

[[:blank:]]91[[:blank:]] works for me, I think. [[:blank:]] matches
both space and tab.
