Parameters

Parameters are special variables used for controlling the execution of tasks. They come in two forms:

string
numeric

Parameters are stored in a file referred to as the parameter file. The parameter file must be present in the local working directory before any parameters may be set in EASI. This file is named:

PRM.PRM

Note: Because the parameters are stored in the file PRM.PRM, they retain their values between EASI sessions.

The master parameter file is located in the PRO directory and a copy of it must be present in the current working directory before any parameters can be set. To get a copy of the master parameter file the following line must be used:

EASI>run copprm

The run command is used to execute a task. In this case, the COPPRM task copies to the local working directory a copy of the master parameter file. The command is entered and is followed by a carriage return (<cr>, Enter).

This following sections describe how parameter values interact with application programs and EASI commands.
