The OMVS command provides an interface to the shell; for example, the layout of the screen and the processing of the function keys.

You can create a customized version of the OMVS command for your own use, by writing a simple REXX program or CLIST that specifies certain keywords on the command. For information about how to do this, see Customizing the OMVS interface and An example of customizing the OMVS command.
