               What You Should Know about the CAS Enabler Aplet
               ------------------------------------------------

The aplet's name is "CAS-Enabler". If the aplet is saved under a different
name it won't work anymore, and the user won't be able to rename it to the
original name. This makes the aplet easily detectable by exam supervisors.

Once STARTed, the aplet's main view (the toggler) is displayed. It can also
be invoked by pressing VIEWS or any view key but NOTE (i.e. SYMB, PLOT, NUM,
SKETCH, SHIFT-SYMB, ...) provided that the CAS-Enabler is the current aplet.
To toggle between CAS enabled and disabled, just press ENTER. Don't worry
about a slight display flicker: a couple of libraries have to be attached in
the process.

While the CAS is enabled, the calculator will behave like an HP40G. Therefore,
no IR option will appear in the transmitting choose boxes. The aplet can run
on a real HP40G, should you be interested in disabling its CAS. This aplet
does not need to be the current one for the CAS to stay enabled. The CAS
command HELP provides a brief description of nearly all CAS commands. A tip
to lock alpha entry mode in the EQW: VARS [NEW] [A...Z] ON ALPHA ON.

When the CAS has been disabled (either temporarily while using the IR or
after a warmstart, ON+SK3) the CAS commands won't be recognised by the parser.
But, the History or user programs in the Program Catalog might contain such
commands - if so, they should never be executed while the CAS is disabled:
some commands would run flawlessly (GAMMA) but others would hang the machine
(INTVX).
