The SYS1.HELP data set contains a member for each TSO/E command. When a user issues the HELP command, information from the HELP data set is displayed. Control characters within each member determine the information that is displayed.

This chapter explains how you can customize the HELP data set by adding new members or adding control characters to existing members.

You can also customize the HELP command to allocate different help data sets for particular languages. See Customizing TSO/E for different languages for information about providing help information in different languages.
