Once you enter the IPCS command to begin an IPCS session, the IPCS subcommands are your main tools for performing dump and trace analysis. These commands allow you to analyze, format, view, retrieve, and copy dump and trace data, and to maintain an IPCS session. You may use subcommands in any mode.

Subcommands are an extension to the TSO command language and can be as long as 32000 characters in length. Common TSO language verbs like LIST (alias L) are used to elicit information displays.
