Invoking Access Method Services

When you want to use an access method services function, enter a command and specify its parameters. Your request is decoded one command at a time; the appropriate functional routines perform all services required by that command.

You can run the IDCAMS program (the access method services operating system) and include the command and its parameters as input to the program. You can also call the IDCAMS program from within another program and pass the command and its parameters to the IDCAMS program.

Time sharing option (TSO/E) users can run access method services functional commands from a TSO/E session as though they were TSO/E commands.

See Invoking Access Method Services from Your Program, for more information.
