About this information
This information describes how to use MVS™ system operator commands for the z/OS operating system.Although you can also perform many of the tasks described in this information using JES2 or JES3commands, this information describes only the MVS (base control program) system commands. Forinformation about commands for other z/OS elements, such as z/OS Communications Server (IP andSNA), DFSMS, JES2, JES3, and RACF®, see z/OS Information Roadmap. For information about commandsfor other software products that run on z/OS, see z/OS Software Products Collection, SK3T-4270.
Who should use this informationThis information is intended for anyone using a console and system commands to control the operatingsystem. This i
