Parameters

 

linkage_name

   The name of a linkage to be defined.
 

input=<>

   Register set that indicates those registers from which a routine
   with this linkage receives input values. This parameter is for
   documentation purposes only.
 

output=<>

   Register set that indicates those registers to which a routine
   with this linkage assigns values that are returned to the
   routine's caller. Registers included in this register set are
   not saved and restored around the call.
 

scratch=<>

   Register set that indicates registers that are used within a
   routine with this linkage. This parameter is for documentation
   purposes only.
 

preserve=<>

   Register set that indicates those registers which a routine with
   this linkage will preserve. Registers included in this register
   set are not saved and restored around a call to the routine,
   since the called routine will perform that task.
