Steff,
Jon already answered your question, but I wanted to add that
Scott Klemement has provided DELTREER4 which includes code
to handle such errors and he also provides tutorials about
use of the IFS

Subject: Qp0lGetPathFromFileID how to check errors in AS400
Hi
I'm reading a line from an IBM created journal and I want to display the name of the file that was accessed. I'm using this API, and getting the results I want when everything is ok.
D GetPathFID PR * ExtProc('Qp0lGetPathFromFileID') D buf * Value D size 10U 0 Value D fileid 16A
D rc s *
c clear buffer 512
c eval rc = GetPathFID(%ADDR(Buffer) c : %SIZE(Buffer) c : obj_fid )
Sometimes I get no result with this API, and the Buffer is empty, and rc gets SPP:*NULL.
After doing some reading on the IBM site, I understand that this means there is an error, but how do I retrieve the error?
Thank you
Steff
