Re: Decimal Place in Character String

I think the "select" will be much more obvious to anyone who comes along down the road.

I was introduced to the acronym "BFCT" (Brute Force Coding Technique) by an IBM'er working on (at that time) CPF at COMMON 30+ years ago and it has come in handy over the years. Usually much clearer and more maintainable than tricky/complex solutions to a simple problem. Code it and move on.

This... to me feels like copy-pasting code. And the more different
d_shift values you have to support, the worse this becomes.

I do suspect this *might* be the best-performing approach. Even if it
is, I don't think the performance gains are worth the verbosification
(and calcification) of the code.

         So are you saying that you would NOT like to see a service
procedure similar to the following [SELECT with 15 WHEN branches,
plus fallback] to accomplish this?

Correct. I would have rather seen the string processing logic as the
guts of the service procedure.

Well, I would rather have seen IBM create %DEC and %DECH to accept
true variable data for the precision and scale parameters.   ;-)
