Writing Extensions

[Mike Kerner]

On the CompileIt thoughts, that was what I was hoping we were going to get
with LCB (We already have Double-XX).  You could make any Mac Toolbox call
in CompileIt, which meant you could build any XCMD/XFCN to add to your
stack, but the syntax was still HC (with some restrictions).

-- 
On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
