Re: *INZSR - I still love you!!!

Putting the initialization up front may be clearer.  Then again, why use 
subroutines at all when inline code may be clearer <sarcasm intended>?

Learning curve for *INZSR? If you can't figure it out in minutes (if not 
seconds), then you're in the wrong profession. IMO.

If I remember correctly, one of the main reasons justifying the addition 
of *INZSR to the RPG III language was that there was no way to fully 
initialize your output fields prior to the first *DETL step of the RPG 
logic cycle. Now, while there /may/ have been enough users of the RPG 
logic cycle around at the V2R3 time frame to justify *INZSR, there are 
certainly a lot fewer cycle users today.

Maybe I'm just in a cranky mood today, but I'm not sure if saving one 
(1) EXSR statement in the typical RPG program is enough of a reason to 
justify having a special *INZSR name in the language. (Sure, there's 
always RESET. But as I suggested earlier, I don't think much of RESET 
either!)

As someone else mentioned, putting the initialization up front is 
clearer than putting it lower down amongst the subroutines.

Cheers! Hans
