ON POWER
========

Function
--------

**ON POWER** allows the programmer to trap and vector program execution
if a user presses the power off key.

Syntax
------

ON POWER GOTO [line no]

or

ON POWER OFF

Examples
--------

::

   ON POWER GOTO 1000

Remarks
-------

This statement causes the OFFVECT locations to be loaded with a vector
so that if operation of the power down key is detected, program
execution occurs from the line number specified.

Operation of the break key, or a syntax error, will cause the vector to
be re-initialised to enable the power on/off switch to function
normally.

::

   ON POWER OFF

This statement also re-initialises the OFFVECT location.
