So MVS TSO, Part 2 starts by teaching you how to use TSO commands for everyday programming tasks. And once you're skilled at using TSO commands, you're going to want to combine those commands into time-saving procedures for the job you do most often. So this book then goes on to teach you how to create procedures using either TSO's procedure facilities -- CLIST or REXX.
