The first action taken at nondedicated or dedicated and sharable RJE workstation is the submission of a signon statement. This statement must be submitted through the input stream as a single-image statement, and cannot be immediately followed by the first job. (Signon is ignored for dedicated, non-shared lines.)

When an RJE workstation signon is successfully completed, JES2 sends a message to the RJE workstation verifying the successful signon.
