A PATHCOM command line spans input records if the last nonblank character is
an ampersand (&). Multiple commands, separated by semicolons, can appear on
the same line. If command parameters are repeated, PATHCOM uses the last
value entered for a parameter.
Interactive Mode
PATHCOM functions in interactive mode when you enter commands from a terminal
keyboard. PATHCOM prompts for a command by printing an equal sign (=). When
you enter a command, PATHCOM executes the command and issues another prompt.
In this example, the first command starts the PATHMON process, the second
command starts the PATHCOM process, the third line shows the PATHCOM sign on,
and the fourth line shows the PATHCOM prompt:
TACL 8> PATHMON/NAME $PM1,CPU 0,NOWAIT/
TACL 9> PATHCOM $PM1
PATHCOM - T9153C31 - (08SEP92)
=
You can group two or more commands separated by semicolons (;). For example,
these two commands can be entered in two ways, as follows:
= command-1; command-2
or:
= command-1
= command-2
Pressing the terminal Break key during the execution of a PATHCOM command
(described in Section 10, PATHCOM Operation Commands) cancels the command;
control remains with PATHCOM and you can reenter the command. Pressing the
Break key in all other instances, including after the PATHCOM prompt appears, returns
the terminal to the TACL command interpreter without terminating PATHCOM. Enter
“pause” at the TACL prompt to return the PATHCOM prompt (=).
Running PATHCOM interactively allows you to monitor the status of the objects,
dynamically start and stop PATHMON-controlled objects, and inform the Pathway
terminal operators about changing conditions using tell messages.
Note. You cannot embed PATHCOM comments in TACL scripts. In TACL scripts, information
enclosed in brackets is interpreted as a function, not as a comment. For information on
including comments in TACL scripts, see the TACL Reference Manual .
