By default, users can issue the TRANSMIT, RECEIVE, SEND, LISTBC, LOGON, LOGOFF, ALLOCATE, ALTLIB, TEST, FREE, OUTDES, PRINTDS, and EXEC commands from READY mode. To limit these commands to certain users, you can use the exit routines provided for these commands.

Users who are authorized to use the OPERATOR command can use the SEND subcommand. You can restrict authorized users of the OPERATOR command from using the SEND subcommand by writing an exit routine. For more information, see the individual descriptions of the exit routines in this document.
