Reading from IFS

I'm am trying to redo an application that was written in KIX by a former
employee.  I want to read the file via rpg from the IFS.  I found a
program I had downloaded a long time ago to read from the IFS.

The problem I'm having is that in testing this little program out, I
have some files(.txt) that it will read and others that I get an 
(error> - file not found) message.

The files are there.  In particular the file that I really need to
read, is receiving the message.

What are some things I can check to determine the problem?  I have
looked at CCSID on the files, but I'm not getting a consistence value 
on the different files that I have experimented with.
