Derek, the override command (OVRDBF) doesn't actually check for the file.
It simply tells the operating system that any programs trying to open file
ABC should instead open MPPMP100 in DXGO.  (I assume you meant that your
TOFILE is DXGO/MPPMP100.)

An error doesn't actually occur until a program tries to open file ABC.  At
that point, the operating system sees the override and attempts to open the
TOFILE.  Typically, this is when your RPG program first loads (or if you
have defined the USROPN keyword for the file, it happens when you issue the
OPEN opcode to the file).

The easiest way to handle this is probably with a USROPN file.  You could
put an error indicator on your OPEN statement, or put a MONITOR block around
it.
