RE: Dynamically allocated tables and %DEALLOC

Even if there are no performance hits, using a *NEW activation group is just bad practice, IMO. If your
memory allocation strategy within a procedure/program is so complex that it is difficult to determine
where to put the %DEALLOC you need to redesigned the process.

But how expensive is it *really*? I am wondering if it is one of those
things where hardware has progressed to the point where it isn't as
noticeable anymore. Note I am not saying don't program for efficiencies,
but I do think about programmer debugging cryptic issues vs. taking certain
defaults to gard ones self.

Has somebody done some performance tests on this so we have more concrete
data?

Using *NEW adds its own set of problems - mostly in performance - because
it is relatively expensive to start a new AG. It IS an easier way to manage
things, sometimes, but it is probably better to be sure you deallocate all
memory yourself that you have allocated.
