Introduction to Tcl
Native Inspect includes Version 8.0 of the open-source Tool Command Language (Tcl),
which enables you to develop macros that can automate debugging operations. You
can write Tcl scripts made up of built-in Tcl commands, and you can write your own Tcl
commands.
Tcl scripts enable you to extend the power and functionality of Native Inspect. Tcl can
help you create custom debugging commands suited for a particular domain or
application. For example, if you are developing a complex application, you could also
provide Tcl commands that aid in debugging the application.
Tcl Version 8.0 is the base scripting engine for Native Inspect. Some new primitives
have been added to facilitate management on the NonStop system.

Using Native Inspect Tcl Commands
The Tcl command-line interpreter is part of Native Inspect, but Native Inspect
commands have priority over Tcl commands.
