Preparing for Xpediter
Introduction, structure of an Xpediter execution; libraries and datasets used: DDIO, loadlib, allocate, log, script. Specifying the libraries to be used. Unattended batch mode, interactive and batch connect modes of execution. Use with CICS, IMS, and DB2.

Getting started
Compiling the program, modifying compilation options; preparing the allocation list for TSO execution, batch execution; invoking Xpediter, supplying run-time parameter values. Connecting to a CICS region. Viewing and setting PF keys.

Using Xpediter commands
Line commands, primary commands, inserted commands; displaying the contents of data fields; modifying data; using MONITOR and REVERSE commands; setting breakpoints before and after executing statements; using COUNT to determine which lines were not executed during a test run; scrolling; using scripts; using FIND; testing values: IF and WHEN; INSERT; INTERCEPT; keeping data fields and their values on the screen; creating and using scripts. Locating CICS program storage areas; file utility primary commands and line commands; DB2 Easy Query menu; Assembler-oriented commands;
