RE: Allocate field with options(*nopass :*omit)

Can you define "tests indicated"?
Does this mean a user complains or that the job takes 20 minutes to complete
when it could have taken 3 minutes?
I think being away of the performance of the way certain things are coded is
critical to RPG IV specifically. Doing something one way might work okay, but
doing it a slightly different way could cut the overhead by a factor of 1000. 
I know a lot of people don't care about performance, and they shouldn't. But I
think a lot of people _should_ know that, for example, using a 64k local
variable in a subprocedure and then calling that subprocedure 10,000 times in
the program is probably not the best methodology.
Sometimes solutions to performance issues are very, very simple. 
I think what happened to performance is that we've been saying in response to:
"What's faster a MOVEL or an EVAL?" The answer is "Who cares?"
And that is still true today. But when something has significant performance
implications, the developer should know about it, and consider it when writing
code. 
RPG IV programmers coming from a C or C++ back ground, tend to think more about
performance. Again performance isn't the end of the road, but it certainly needs
to be watched.

Yes.  But, I normally do not apply this rule if I plan to create
commonly use export procedure.

Lim,

Number one rule of performance when coding: don't worry about it unless
testing shows it to be a problem.
