Getting Started With TACL
The Compaq Tandem Advanced Command Language (TACL) program, the command
interpreter for the Guardian environment, is the primary interface between you and the
Compaq NonStop™ Kernel operating system.
The TACL program lets you designate special function keys and create macros:
•
Assign an alias, or alternate name, to a TACL command or an application. You can
execute the command or application by simply entering the alias name.
•
Write a macro to execute TACL commands or run an application. A macro is a
named sequence of one or more TACL commands stored in an EDIT file. Entering
the macro name invokes the command sequence or application.
•
Define your function keys to execute TACL commands, invoke macro and alias
definitions, and run applications.
•
Write programming routines to perform complex operations.
See Section 5, Defining Function Keys and Writing Macros
, for more information.
The TACL program can also be used as a programming language, but this is not
described in this guide. See the TACL Reference Manual and the TACL Programming
Guide for more information.
The Safeguard subsystem is a group of software security programs that supplements the
system security features that is commonly used to secure user logons to TACL sessions.
