Re: What are the benefits of ILE?

Brad,

Just to toss a little gasoline on the fire, wasn't this "write once, use
everywhere" handled by /COPY since the S/34?

As someone else posted, make it a callable program.

IMHO, the purpose of ILE was not to replace /COPY or callable programs.  The
machines have gotten faster so the performance hit on a CALL becomes a moot
point.  AFAIK, the purpose of ILE is in file scopeing. Overrides and ODP's and
commitment control and all that.

I think that we all must take a historical perspective on the IBM midrange
systems and -why- certain features are made available.

IBM creates a midrange system for maybe 3 customers.  Like the U.S. Postal
service or Farmers Insurance or Costco.  Now in order for a manufacturing plant
to be cost effective it must produce at or near plant capacity.  So the excess
machines made for the chosen few are unleashed to the masses.

Now because one of the chosen few have a software design problem, ILE file
scopeing (at the OS level), saves the chosen few development bucks and keeps 
them
in the IBM fold.

IMNSHO ILE is not for the masses but the chosen few.
