RE: ILE Propoganda

You can be more efficient with ILE also.  Let me redefine the example below
with some more complexity.  Let's say that getAllocatedUnits(item_num)
returns a numeric and you need a character, for whatever reason.  You can
wrap getAllocatedUnits(item_num) with %char and have the result put in
units_allocated which is 5 alpha numeric.  And you can do this all in one
line! 

D units_allocated      S        5  
D item_num             S       10


EVAL   units_allocated = %char(getAllocatedUnits(item_num))

Rob,

My argument would be that I like being able to use the results of the
procedure in an expression. I think that:

EVAL   units_allocated = getAllocatedUnits(item_num)   , is much more
readable then:

CALL     'PGMXXX'
PARM                         item_num
PARM                        units_alloc

In my opinion, the coding is more self documenting and elegant.

Just my 2 cents,

Mark

Yes, but the earlier question was how would that be different than a CALL?
See, if you change the called program wouldn't that be just as seamless, if
not more so, as changing a service programs subprocedure?  Granted I would
use the ILE approach, but this a strong argument to counter.

Local variables are nice, but the real beauty of using procedures and
modules is the reusability and maintainability that you gain as time goes
by.

You might ask your new ILE programmer if he/she has ever had a situation
where a calculation or routine needed to be modified but all the places
where that calculation was coded either weren't known, all of the weren't
found, or even if they were all found, how much time did it take to find
them all and change them all.  And then of course not all those
calculations were coded the same so the programmer had to change them
differently to achieve the same result.

Once you've developed your store of procedures and modules, the maintenance
effort is greatly reduced.
