Hi Scott,

As always - spot on.
Using o_ccsid solved all problems and the program is working as expected.
And yes - I use o_ccsid=0, and that's confirmed working on ccsid 278 and ccsid 277 lpars with national characters involved!

Thank you for your time and effort - I actually read up on fopen ahead of posting, but until your explanation I did not understood the difference between ccsid and o_ccsid.

Best regards

Subject: Re: RPGprogram: how to use fopen with various CCSID's

Use o_ccsid instead of ccsid. Also, consider whether you really want to hard-code 278, or if you'd be better off using o_ccsid=0 (0 means current job's ccsid).

The ccsid= keyword is legacy cruft -- don't use it. It was for old releases before the IFS supported CCSIDs, so what it does is convert the CCSID to a corresponding code page, and then uses that... this won't work with anything that requires multiple code pages (such as Unicode.)

I need to read thru a bunch of IFS-files in an rpg-program to locate
some items.

Using fopen( %trimr( file ): 'r, ccsid=278' ); seems to work pretty
well until I encounter a file with CCSID=13488.

That one gives me an errno=3490=Conversion error.

If I modify the fopen to fopen( %trimr( file ): 'rb' ); binary mode
makes me get thru the open but then I have to translate all the data by myself.

What is the proper way of dealing with this?

I am expecting to find files in various ccsid's like 819, 37, 819,
278, 13488, 1252 etc.
