I have found a few books usefull but none appear to cover the IIe yet. I have
a II and I can't believe that the IIe manuals don't tell you how to disable the
ctrl-c function. I recommend getting a hold of the II manuals if you want to 
do any serious programming. All the features of the II have been supported on
the IIe. It is impossible to modify any of Applesoft when you have it in ROM.
They do leave you 1 user definable command! This is the & command this command
causes a JSR $3F5. You can then create a JMP to your routine and use an RTS to
return control to BASIC. Well, well look what Apple says about the & command
they say, "The ampersand (&) is intended for the computer's internal use only
it is NOT a proper APPLESOFT command. This symbol, ....." This looks like an
excuse for not explaining any thing that requires advanced knowledge.

To disable ctrl-c you must insert 2 statements. (Caution! Do not use this
with any Applesoft program containing GET statements.
XXXX ON ERR GOTO YYYY
YYYY RESUME
To re-enable crtl-c use a statement with a POKE 216,0.
