Re: Display screen in a program, not in batch.

Everyone's solution was so right in the end.  I did as suggested and the 
program works nicely.  I don't use CL much but this program already had a 
'ZZZ' flag for silent running so it was easy to condition on "not silent 
running".  Thanks to everyone for an easy answer to my problem.

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)
