USE: Invoking a Constraint Prototype

The USE keyword allows you to invoke a previously defined constraints prototype. The format of the USE keyword is:

(any   level selector or  DEFINE) 

(optional  constraints)

USE=name

(optional  overrides of  prototype values)

The name variable must select a prototype that has been previously defined. The USE keyword is equivalent to specifying all of the constraints that are specified in the named prototype definition.

The following example shows a prototype definition and two invocations of the defined prototype:

SYSTEM_DEFAULTS 

   (any  defaults)

MODE=INCLUDE

DEFINE=PRODZ	  *  Define   prototype named  PRODZ 

   MAXBUFND=60	MINBUFND=25
   LSR
   MINBUFNI=20	MAXBUFNI=50
   HIPERSPACE    DEFER  SHRPOOL=3
   MSGLEVEL=6
   ...
   ... (other constraints)
   ...

JOB=PAYROLL
   USE=PRODZ	*Invoke  all PRODZ  constraints
   MAXBUFND=80	*Override PRODZ   MAXBUFND

PROGRAM=XYZ+
   USE=PRODZ	*Invoke  prototype PRODZ  with  no  overrides
