HUNTER System Files
===================

HUNTER's system files are not true files in the CP/M sense. They are
built-in utility programs designed to support use of the computer. The
function of each is described below.

File Directory
~~~~~~~~~~~~~~

Displays a list of filenames. The use of wildcards is supported. See
:ref:`wildcards`.

File Status
~~~~~~~~~~~

This function displays the file status, read/write or read only, file
size and remaining file space. See :doc:`../file-manager/file-manager-commands/stat`.

Basic Interpreter
~~~~~~~~~~~~~~~~~

Access to HUNTER'S Basic interpreter is provided with this option. See
:doc:`../basic-programming/index`.

Initialise Communications
~~~~~~~~~~~~~~~~~~~~~~~~~

The parameters of HUNTER'S industry standard RS-232/V24 interface may be
changed for compatibility with additional external equipment. See
:doc:`../communications/index`.

Initialise Clock
~~~~~~~~~~~~~~~~

The date and time of HUNTER'S internal calendar clock may be set with
this function. Calendar maintenance is completely automatic once the
correct date and time have been entered. See
:doc:`../file-manager/file-manager-commands/clck`.

Terminal Emulation
~~~~~~~~~~~~~~~~~~

HUNTER emulates a simple CRT terminal. The communications baud rate and
protocols are first initialised with 'INITIALISE COMMUNICATIONS'
function. See :doc:`../communications/terminal-emulation`.

Edit
~~~~

This activates the text editor. See :doc:`../editor/index`.

Keys
~~~~

Operation of the function 'KEYS' displays the alternate function key
display line, as follows:

::

   DIR STAT INP SAVE TYPE REN SEND KEYS

Further operation of the function 'KEYS' will return HUNTER to the
original function key display line.
