How to Invoke POI Command Processors

You can invoke POI command processors as follows:

By including them in a TSO CLIST or TSO/E REXX program.
By issuing them in ADDRESS TSO host environment instructions in an OPS/REXX program. The TSO host environment must be present to execute a POI command in an OPS/REXX program.
By including them in a UNIX REXX program running under UNIX System Services (USS).
By issuing them as NetView commands or NetView REXX functions.
By issuing them interactively in a user TSO session.
By specifying them in a z/OS parameter string as input to a TSO/E CALL command outside of the TSO host environment.
By specifying them as the PGM value on the EXEC statement in a batch job step with parameters specified as the PARM value. For an example, see Issuing POI Commands in Batch Mode in this chapter.
By including them in the //SYSTSIN DD in a batch job step that is running the TSO TMP in batch mode. For an example, see Issuing POI Commands in Batch Mode in this chapter.
