The Remote Execution client can send commands to the TSO Remote Execution server by the following methods:
With methods 1 and 2, the TSO Remote Execution server executes the request and passes the password to MVS™ for verification. (REXEC commands require a password.) When these methods are used, skip Step 3.
With method 3, to enable an RSH client to send RSH commands to the TSO Remote Execution server without specifying a password, Step 3 is required.
