Cor- it works too!

For anyone else trying it, don't forget to set the load/exec addresses of
BASIC to 8000 before running it!

Typing 
 PRINT SIN(RAD(30))
gives the right answer after a second or two of calculation.

Interestingly (not a complaint!) many other operations give "No room", even
though HIMEM, LOMEM, TOP, PAGE all look right. Even just
 P%=1
which of course doesn't need any new variable allocation, so it must be
something in the expression evaluator wanting some stack maybe?

A most impressive piece of software, I look forward to seeing how it
progresses,
