IBM doesn't support all extensions for Regular Expressions. I have also
been caught in that testing against web RE testers. You have to make
sure you select one that is only using POSIX.

If you stay within POSIX standards, you should be OK on the IBM i. That
backwards slash doesn't look familiar.

Trying to use regular expressions in RPGLE.

Have the following:
string = 'Some stuff A410920 other stuff' + x'00';
in@pattern = '[AaZz]{1}[Aa0-9]{1}\d{5,6}' + x'00';
preg = %addr(regex_t);
pmatch = %addr(regmatch_t);

// Compile RE
rc=regcomp(preg:%addr(in@Pattern):REG_EXTENDED);

// Execute RE
rc = regexec(preg: %addr(string):
nmatch: pmatch: 0);


I am trying to match/find A410920 in the string.

In this case - it does not find a match: If I put this same example in
one of the web based regular expression testers - It matches fine.

If I change the in@pattern to '[AaZz]{1}[Aa0-9]{1}' + x'00';
it will match the A4 portion of the string.

Can't seem to figure out what is wrong. Any help would be appreciated.

Thanks
