Override problem

I am having a problem with an override data base operation. My file is
internally defined:

        FInfile    if   f10000     5aiDisk    Infds(Dsfile) Usropn    

In the program I override to the desired file:

         * Override and open file

        C                   Eval      %subst(Cmdovr:23:21) = %Trimr(Lib) +
'/' +    
        C                             File

        

        C                   Call      'QCMDEXC'

        C                   Parm                    CmdOvr

        C                   Parm                    CmdLen

        

        C                   Open      InFile


When I run this on our development box, everything is fine. However, when I
run this on our production box, I receive the following error:

        Message ID . . . . . . :                CPF4101
Severity . . . . . . . :                40              
        Message type . . . . . :                Escape

        Message . . . . :   File  in library  not found or inline data file
missing.   
        Cause . . . . . :   The file was not opened.  The reason code is 01.
The       
          reason codes and their meanings are as follows:

            01 - THE LIBRARY DOES NOT EXIST.


The file and library do exist, there aren't any typos, the override command
is correctly executed, displaying active overrides shows InFile being
overridden to the correct file.

If I call the program and specify *LIBL for the library, I receive the exact
same error message. If it said "file not found" I would understand. But how
can *LIBL generate this error?!

Any help would be appreciated.
