RE: ILE Propoganda

["hartawan reksodiputro" <jeanhartawan@xxxxxxxxxxx>]

The next question then, "How do you convince the other programmer - the 
corporate developers - to use it, CALLP-ILE, instead of using CALL?"

In terms of Performance vs "more-familiar-easy-to-change" the subroutine 
program, sometimes it's difficult to draw a solid line, that will then make 
"the user", at least, try the ILE approach.

If the differences in performance is such a fraction, "the user" will most 
likely choose the "faster" approach - which is more familiar to them. Thus, 
at first, the ILE approach seems to be a very effective way but not that 
"efficient", in terms of handling the short-term businees needs.

But, as the business itself grow, the requirements for the corporate 
application are also changed and become more complicated. That will lead 
them, probably, as I encountered, into a recursive problem. Where the 
subroutine is called in such a way, that it requires to be called multiple 
times in a stack.

Then come a savior, the real solution, which is to use the ILE approach. 
Procedure or function in a maintainable modular basis.
There's no other way to deal with this problem gracefully, except using the 
ILE approach.

It's not a recommended approach to "give-an-example" of how ILE can help 
"the user" doing their business better. But, it can be an inspirative 
"reminder" on how to cope with the unexpected condition in the future.

To make them understand, that once you know how to create a procedure, bind 
into a service program, than it'll be just as maintainable as the other 
subroutine program.
