Re: Weird issue with a display file

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

James,

DSPPGMREF only shows the file as it was known at compile-time.  It does 
NOT mean that it's going to use the same library at run-time.

At run time, it does one of the following:

1) Uses the library specified in an override (OVRDSPF) if available.
2) Uses the library specified via EXTFILE, if available.
3) Uses *LIBL

I don't remember exactly when EXTFILE was added to the language -- but 
the same exact symptom could be created with OVRDSPF.
