.. Scott is right o_ccsid is your friend. Nevertheless remember to set your job’s ccsid , otherwise the =0 trick will not works

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.
