The program fails because it tries to open the display file upon startup.  The
easiest way to fix this is to put the display file under user control (UC in 
position 71-72 for RPG III, UsrOpn keyword for RPG IV) and then explicitly
OPEN the display file just before using.  This will still fail in batch if the
OPEN ever executes, so you might want to consider having the calling
CL pass a parameter indicating whether the environment is batch or
interactive and don't do the OPEN if batch. (RtvJobA  TYPE(&Type) - 
0 = Batch, 1 = Interactive)
