Re: INZ in all D-specs : Was Problem with moving Data Structures

As has been pointed out in the past, fields and DS's in the D-specs are
automatically initialized, *unless* you specify the STATIC keyword (only
valid for procedure variables). Therefore, from a performance standpoint, I
tend to declare very large DS's etc. as STATIC and then explicitly
initialize them immediately prior to their use. That way, if the DS isn't
actually used every time the procedure is called, it won't be needlessly
initialized.

You have to be careful with Reset if you are writing modern ILE RPG. (Local

I had a program that was using a bunch of static storage but I had nothing
declared in static. I talked to IBM and it turns out all the values for the
Reset are stored in static storage even though the reset is to a variable
in
local storage. Why I have no idea.
