Product Components and Operation
The EMCOM Interpreter
The EMCOM interpreter processes emulator commands and directs the operation of the
emulator according to those commands. Both the central operator and the terminal user
can type in commands. EMCOM can also accept commands from a file.
Type in the following command to execute EMCOM:
run-parameter
specifies a parameter for the TACL (Tandem Advanced Command Language) RUN
command (see the NonStop Kernel Operating System Programming Manual).
process-name
specifies the name of a particular EM3270 emulator process. When you do not
supply a process-name, EMCOM uses the $EM process name for the session.
command
specifies an EMCOM command. If you type more than one command, use a
semicolon (;) to separate the commands. When you type one or more commands
with this command, only those commands apply to the current emulator session.
That is, any specified IN file is not read and no commands from the keyboard are
accepted.
Modes of Operation
When you type the command to run EMCOM without an IN or OUT parameter,
EMCOM runs in interactive mode. It displays a close brace (}) as a prompt character
and accepts commands from the keyboard. When you type the command with an IN
parameter, EMCOM reads commands from the file specified with the IN parameter.
The output of EMCOM is displayed on the terminal screen unless you use the OUT
parameter with the command to run EMCOM. You can use the OUT parameter to store
EMCOM output in a file named with the parameter. However, EMCOM continues to
display error messages on the terminal when an OUT file has been defined.
