Joseph,
Now days I rarely do DB IO from C. Instead, I use RPG to handle that
and do the fun stuff in C.
Opening with fopen("file", "r+") is a text mode open for both reading
and writing. You probably want to use "r+b" for binary mode reading
and writing.
Also, you might want to signup for the C400 mailing list at

Subject: ILE C Program Write Access
Hello all,
We have just recently installed ILE-C on our AS/400(v4r3) and
are
having difficulty opening any files with write access with the
compiled
programs. Any files on the system can be opened and read without
problems. As soon as I set the fopen flag to allow write access the
open fails with errno = 3101. I have tried this on files that I
myself
have create, and also have tried running the program as qsecofr with
the
same results. The following is the dspfd output for the file and the
open command in the code. What am I missing?
Thanks,
Joe Eaton
Open command that fails with errno = 3101
if ((bciin = fopen("eatonj/pg2001_bci", "r+")) == NULL)
