DEF ARG | Define Temporary ARG Value

## Format

DEF ARG(nnn)="value"

Where:

nnn | Argument number to be changed.
value | New value to be returned for the specified ARG.

## Description

The DEF ARG directive can be used to change the values returned by the ARG function. This directive allows you to temporarily override the value normally found following the -ARG parameter on the Command line that launched the system.

(The DEF ARG(nnn) function was added in PxPlus v6.30.)
