That is not very neat from Basic, because when doing a CALL you can't 
control which character you put in the A reg. A will become equal to the 
high byte of the called address, $C3, so calling 49920 will also print a 
"C" in the top left corner of the screen.
Apple's preferred way is to call $C300 with $8C in the A-reg, but as we 
cannot do that in BASIC, redirecting the output vector with PR#3 is the 
second best way.
