A TSO/E user can invoke the shell automatically when logging on to TSO/E. When logging on, you can invoke the shell by adding one of the following to the TSO/E logon panel:

• The OMVS command.

  Example: If the default options are required:

  Command ===> OMVS

  Or:

• The name of the REXX exec that contains an OMVS command with operands for required options.

  Example: If the exec name is MYOM:

  Command ===> MYOM

Tip: You might want to invoke OMVS from ISPF for the following reasons:

1. It is faster to invoke an ISPF dialog such as OEDIT or OBROWSE because ISPF does not need to start and stop to run the command.
2. It is not necessary to type *** and press <Enter> after running an ISPF dialog; control returns to the shell.
3. You can use split-screen support when using an ISPF dialog.
