Re: regcomp/regexec problem

Hello Thomas,

I use regex to check mail addresses. But it is necessary to set the system-value QLOCALE to the correct value. I'm living in the german-speaking part of Switzerland and my value is /QSYS.LIB/DE_CH.LOCAL

Before that change, I had to use iconv() as mentioned earlier.

Best regards

Jan

Hi Danny,

That is exactly what I am faced with. regcomp() works, but regexec()
fails and I still have no idea why.

Hi Thomas,

thanks for this info.
Have included this and now the regcomp is working, but still the regexec is
not working.
We the program with a valid ordernbr and still the regexex returns a 1.

Program source as attachment

Any other ideas.

Already copied a number of examples but none of them seems to work. Is there
something special about this
That I'm overlooking?

It is correct that LOCALETYPE is specific to C/CPP. I assume that I actually
wanted to add the following URL, which describes the usage of
setLocale():

Hi all,

Taken some of your remarks into account and this is the followup:

To Carsten,

Have checked this locale stuff and settings QLOCALE =
/QSYS.LIB/EN_BE.LOCALE Job CCSID = 1148 Seems a valid combination.

To David,

Like to follow the regcomp/regexec path instead of the SQL.
But have tried your expression and got now a return code 11. Even with
the extended flag on.

To Thomas,

Maybe I'm missing something but LOCALETYPE(...) seems only to exist on
the compiler command for C/CPP.

General, I'm still searching
Any other ideas

BR+
Danny

Hi Danny,

A possible explanation can be found here (regcomp() and regexec()
functions are Locale Sensitive):

Cheers,

Hi,

Want to validate a field with the regular expression support.

Took a look at the example in "Who Knew You Could Do That with RPG IV"
redbook and wrote the following code:


ctl-opt main(main) dftactgrp(*no);

/copy cregexpr

dcl-proc main;

dcl-pi main extpgm('STL9120P');

PxOrderNbr char(8);

PxOK char(1);

end-pi;


dcl-s RegPattern varchar(50);

dcl-ds preg likeds(C_regex_t);

dcl-ds pmatch likeds(C_regmatch_t) dim(1);

dcl-s rc int(10) inz(9);

dcl-s cflags int(10);


cflags = REG_EXTENDED + REG_ICASE;

RegPattern = '^[A-Z0-9-_]$';

rc = regcomp(preg: RegPattern: cflags);

if ( rc = 0);

rc = regexec( preg: %trim(PxOrderNbr): %elem(pmatch): pmatch: 0);

PxOK = %char(rc);

endif;

regfree(preg);

return;

end-proc;


When calling with first parm = '12345678' it return allways 1 (not equal).

The regexec seems not to work. So what I'm doing wrong, where I have

failed?
