ENDUPLEX -- Startup/Endup control lexfile. Adds ENDUP, ENDUP$, and
STARTUP$ to BASIC.

Size: 252 bytes.

The built-in STARTUP statement puts a string of BASIC commands into a
special buffer that gets executed automatically at power-up. ENDUP is
similar, but the specified string gets executed at power-down. This is
true whether the power-down is due to pressing the OFF key, execution
of OFF or BYE from the keyboard, or even if the HP-71 times out and
automatically goes to sleep after ten minutes of inactivity.
(Inactive in CALC mode, but active in FORTH mode).

ENDUP$ returns the contents of the ENDUP buffer.

STARTUP$ returns the contents of the STARTUP buffer.
