Show all headers | View raw

I didn't know what search terms to type in.

I'd like an all applesoft (I have 6502 code) program
that will output the ascii value of the character stored
in 40 column mode X,Y position.


10 vtab 10:htab 20:print "X";
20 y=10:x=20:gosub 1000:rem get char value
30 print asc(g)

X


1000 rem use X and Y to determine ascii value, and
1010 rem return in variable G
