Help with SQL Error -648

I'm having problems with the following SPL in informix 7.23.uc1 on hp-ux 10.20, but it seems to work fine on informix 7.22.uc1 on hp-ux 10.10 CREATE PROCEDURE test_spl( ) DEFINE Test_Message CHAR(50); set debug file to '/tmp/proc.debug'; trace on; LET Test_Message = 'Test Message'; SYSTEM '/bin/echo hello'; End Procedure ; There are two problems both I belive are caused by the same thing. First the Debug gives me SQLCODE -648 ISAM Code -13 Permission denied. Second SYSTEM command gives SQLCODE -668 ISAM Code -13 Permission denied. These errors only occur if you are running from a client system and are not connecting as informix. If anyone has an idea about what this may be, I would like to here from them. Thank You Michael J.
