Command interpreter front ends
These commands are the command interpreter front ends themselves.
They present different user interfaces for the same underlying
command interpreter engine.
cmd- a simple front end that reads from its standard input and writes to
its standard output, which is designed to have a low memory "footprint",
which is good for when one needs a non-interactive command interpreter (as
one does for background commands and command pipelines, for example).
pmcmd- a front end that has a Presentation Manager user interface, with
on-line help in the usual PM style, and command line recall and editing
using ordinary PM controls.
textcmd- a front end that has a text-mode user interface designed for interactive
work that provides such features as console-style command line recall and
editing.
Built-in commands:
The commands in this section are built in to the command interpreter
itself, either because they require access to the internal data structures
of the command interpreter (such as the alias list) or because they need
to modify properties of the command interpreter process (such as its
current code page). They cannot be replaced by other executable or
command script files.
