Entering operator commands

Operator commands are entered and VTAM® messages are received at the system console or the remote network console.

VTAM operator commands and their formats are described later in this topic.

The length of a VTAM operator command that can be entered at a console is limited by operator command input devices, certain operator application programs, the VTAM program operator interface, and VTAM itself. In most cases, VTAM requires operator commands to be entered on a single input line. Two exceptions are:

If you need to enter more start options than will fit on one input line, end the line with a comma. Then VTAM prompts you for additional start options.
If a command that exceeds VTAM's command length limit is entered on the input line, the command is rejected even though it might fit on the input line. A message indicating the additional length limitation imposed by VTAM is issued.
VTAM's command length limit can be reduced if PPOLOG=YES is specified in the START or MODIFY PPOLOG commands.
