The Command Entry
Facility
The Command Entry facility provides:
An alternative to OCS for entering NonStop NET/MASTER MS commands
A means of entering external utility commands without having to type the utility
name every time
Entering commands from the Command Entry facility differs from entering
commands from OCS in the following ways:
When you enter a command from the Command Entry screen, the results of the
command are returned to you in a continuous sequence; the results are not
automatically intermixed with unsolicited messages arriving at the same time.
When you enter a new command, the response from the previous command is
cleared from the screen.
Commands, responses, and (optionally) unsolicited messages (see “Receiving
Unsolicited Messages” in this section) are saved in a capture buffer, which you
can scroll through and print.
Commands are saved on a command stack, which you can display. You can select
previously entered commands from the command stack for reexecution, and you
can delete commands from the command stack.
The Command Entry facility automatically routes a command for execution at a
remote NonStop NET/MASTER MS system if you supply the name of the link that
connects it. In OCS, you must use the ROUTE command.
The Command Entry facility can automatically send a command or command
string for execution by an external utility if you supply the name of the utility or
the name of a session that you have established with the utility. You do not have
to reenter the utility name or the session name each time you send a command to
the utility. In OCS, you must refer to the utility name or the session name each
time you send a command to the utility. Furthermore, if you are accessing the
utility through a session name, you must use the OPSYS command.
If you are receiving event messages at your OCS screen at a rate high enough that
NonStop NET/MASTER MS keeps taking control of your keyboard to write to the
screen, entering commands from the Command Entry facility can alleviate this
problem.
The disadvantages of entering commands from the Command Entry facility are that:
There is no persistent critical message area for non-roll-delete messages, so critical
messages might be lost while in the Command Entry environment.
The display of responses to commands is slower than in OCS.
