RE: usropn files and service programs

["Bob Cozzi" <cozzi@xxxxxxxxx>]

What you "should do" is up to you.

In service programs, the globally declared files are opened when the first
subprocedure in the service program is called. They remain open until they are
explicitly closed  OR  the service program is unloaded.

Files in service programs (as with regular programs) that contain the USROPN
keyword, are open by an OPEN opcode and remain open until they are explicitly
closed  OR  the service program is unloaded.

Anybody know where I can find the ibm advice mentioned below?  Just
curious on the reason behind it.

<clip>

afaik the default advice of ibm is that files in a service program
should be defined usropn. but if i open and close the files on every
procedure call the batch program is really slow.
