#^A reads in as 501, instead of 1. if I had wanted 501,
I would have typed #/A.
#^A means control-A. "That character that is generated by holding
down the control key and typing A". In MacLisp that is the number 1,
on a LispMachine that is the number 501. There is no other control-A
on a LispMachine.
Indeed 501 can also be generated by #/A. That means "A with the control
bit set". This is the fixnum 301 in MacLisp.
If you want the number 1, then you mean the LispMachine character
called "down-arrow". The way to get this is #/.
