Re: CL - convert to uppercase?

I'd use the "Convert Case (QLGCNVCS)" API to convert lower to upper in a
CL program. I published sample CL code that converts upper to lower in my
newsletter. If you've got a Pro membership to the iSeries Network, you

It's pretty simple.  To change it to convert the other direction (lower to
upper) change the 3rd part of the control block so that it's all zeroes.

For example, right now my sample code lists this:

     CHGVAR VAR(&CTLBLK) VALUE(X'00000001+
                                 00000025+
                                 00000001+
                                 00000000000000000000')

To make it convert the other direction, do this instead:

     CHGVAR VAR(&CTLBLK) VALUE(X'00000001+
                                 00000025+
                                 00000000+
                                 00000000000000000000')

One nice thing about this API is that it's able to use the job's CCSID.
Unlike techniques that rely on QDCXLATE or RPG's XLATE or %xlate()
capabilities, it'll work properly no matter what language your system is
configured for....  without any changes...

It's the best approach I've found.
