RE: Programming Performance

["Zukowski, Donna" <Donna.Zukowski@xxxxxxxxxxxx>]

Hello!  

We use this quite often in interactive applications.  Typically, we will
code "one time only" (field definitions and such) in *INZSR, and create
another subroutine that initializes all other variables.  This second
subroutine is called every time the program begins.

Not setting on *INLR is of great use whenever you have one program that
repeatedly calls another since you save on the opening/closing of the
files.
