Using TACL as a Command Interpreter
Using TACL as a Command Interpreter
The TACL program is most often used interactively as a command interpreter:
1. After system startup, your system manager or operator starts a TACL process from
the TACL program file for each terminal, including yours, connected to the system.
(The TACL program file is on the system disk $SYSTEM.SYS
nn .TACL, where nn
is a two-digit number.)
2. You log on to the TACL process at your terminal to access your system (see
Logging On With TACL on page 2-3). If you are connected on a network, you can
also start a TACL process on another system (see Section 4, Starting and
Controlling Processes With TACL ).
On systems running Safeguard software, your system manager can optionally
specify that some or all terminals be controlled by Safeguard. At these terminals, the
logon procedure differs from the standard TACL logon. A successful Safeguard
logon results in a TACL prompt only if your system administrator has configured
the system to do so (see
Logging On With Safeguard on page 2-9).
3. After you log on at your terminal, you can enter TACL commands at your terminal
keyboard. As a command interpreter, the TACL program lets you enter TACL
commands, run system utilities (such as TEDIT or Peruse), and run any application
that you might need to do your job.
Entering TACL Commands
You can enter interactive TACL commands only when the TACL prompt (>) appears on
your terminal screen, which indicates that TACL is waiting for you to enter a command.
Type your command after the prompt, then press Return.
To use the TIME command to make the TACL program display the system date and
time:
You must end each TACL command line by pressing Return. Examples in this guide
assume that you press Return at the end of each command line.
Most TACL commands are short (fewer than 80 characters). They can, however, contain
up to 239 characters on one line. To enter commands longer than 239 characters:
1. End each command line (except the last line) with an ampersand (&).
The TACL program redisplays its prompt with the same line number and an
ampersand at the beginning of the continuation line.
2. Continue entering your command after this ampersand on the continuation line.
