Understanding common parameter descriptions

The following describes the parameters and concepts common to the macros described in this topic.

Parameter

Description

address

The name of the field that contains the value of the parameter. The following example illustrates a BIND macro where SOCKNO is set to 2.

     MVC   SOCKNO,=H'2'
     EZASMI TYPE=BIND,S=SOCKNO

*indaddr

The name of the address field that contains the address of the field containing the parameter. The following example produces the same result as the example above.

     MVC   SOCKNO,=H'2'
     LA    0,SOCKNO
     ST    0,SOCKADD
     EZASMI TYPE=BIND,S=*SOCKADD

(reg)

The name (equated to a number) or the number of a general purpose register. Do not use a register 0, 1, 14, or 15. The following example produces the same result as the previous examples.

     MVC   SOCKNO,=H'2'
     LA    3,SOCKNO
     EZASMI TYPE=BIND,SOCKNO=(3)

'value'

A literal value for the parameter; for example, AF='INET'
