RE: ILE Propaganda

["Saunders, Martin P" <Martin.Saunders@xxxxxxxxxxxxxxx>]

To be fair, this has always been possible in RPG/400 by using /COPY
subroutines.  Although I would expect the ILE procedure method to be more
efficient as well as providing the other benefits of local variables,
parameter checking, prettier code etc.

Yes!  My job today is to update 71 RPG OPM programs.  They all call the 
same subroutine, perhaps 5 - 10 times per record, over hundreds of 
thousands of records.  If the subroutine were an external program call, the 
programs would be too inefficient to finish in the time allotted.  Thus, 
the subroutine was copied into every program as it was developed.

If this routine had been coded as an ILE procedure, all I would have to do 
is change the procedure one time, and then recompile.
