/*SIGNON statement
Purpose: Use the /*SIGNON statement to tell JES2 to begin a remote job stream processing session. For non-multi-leaving remote stations, the terminal transmits the /*SIGNON statement alone as part of the initial connection process.
Note: The remote terminal access processor processes the /*SIGNON
statement if it appears in a job stream. When the terminal access
processor processes the /*SIGNON statement, the line being processed
is restarted.
Systems network architecture (SNA) remote work stations must use the LOGON command instead of the /*SIGNON statement to notify JES2 of a connection request.
