Re: Question about Code pages and writing file directly to IFS with RPG program

Thomas

your method only solves half of the problem because the same problem exists
in
naming fields.

On a CCSid 37 systems field names like ##NO @@NO, $$NO are allowed but
on a CCSid 277 system (danish) they are NOT and but must be renamed to
ÆÆNO, ØØNO and ÅÅNO in order for one to be able to compile the program.

John,

As you already figured out, using different constants depending on the
CCSID of the current job is not a good idea. Here is a demo that shows, how
to use Unicode literals. It produces the following output:

Job running with CCSID 273:

¬hex-constants|
[unicode-constants]

Job running with CCSID 37:

[hex-constants]
[unicode-constants]

You see, the Unicode constants work for both CCSIDs.

Please refer to my posting from Tuesday to get a copy of the UNICODE
command.

Thomas.

Betreff: RE: Question about Code pages and writing file directly to IFS
with RPG program

Thanks for the info.
The program is always compiled using CCSID 37 I do not use constant
character [ and ] instead I use variable fields where I load their values
based on the CCSID of the system where the program is running

EVAL W$BrktL = X'BA'
EVAL W$BrktR = X'BB'

Then I tried (without success) using different variations of this:
C WHEN W$CdPage = 284
C EVAL W$BrktL = X'4A'
C EVAL W$BrktR = X'5A'

Then I figured this was not the correct/best solution for this. There has
to be a simpler/better way As I still need to get all of the Spanish
characters in the spool file to map correctly as well
