ORA-1405 Error w/ORACLE7 and Pro-C, HELP!

I am running Oracle 7 and Pro-C Version 1.5 on an IBM RS6000 with AIX.

At the top of page 4-5 in the *Programmers's guide to the ORACLE Precompilers Version 1.5* it states:   

    When MODE={ANSI13 | ORACLE}, you can SELECT or FETCH nulls into a     host variable not associated with an indicator variable...

.
.
.

    However, when MODE={ANSI | ANSI14}, if you SELECT or FETCH nulls into a     host variable not associated with an indicator variable, ORACLE issues

       *ORA-01405: fetched column value is NULL.

I have set MODE=ORACLE in the compile line and I still get ORA-01405. The only way that I can *NOT* get the error is if I use an indicator variable (contrary to the documentation) or use the NVL option.

Any ideas?
