Chapter 2 Utilities and Tools

Table of Contents

This section describes the MPE/iX user interface to show how user programs can programmatically access MPE/iX features and provides an introduction to utilities and tools. The information is presented as an overview on a conceptual level. For detailed information on programmatic access, refer to Command Interpreter Access and Variables Programmer's Guide (32650-90011).

Programmatic access to MPE/iX allows you to use command interpreter (CI) features in a program without having to enter break mode. With the available techniques, you can develop sophisticated, automated subsystems to run under MPE/iX. The techniques include:

Using MPE/iX programmatic interfaces, command files, and user-defined commands (UDCs).
Performing variable dereferencing, concatenation, string substitution, recursive dereferencing, and expression evaluation.
Using Job Control Words (JCWs) and variables.
Using the MPE/iX Help facility for commands, command files, and UDCs.
