If that was what you were wondering about, then here's a little 
addition. This can be shortened because of the way the calculator 
reads logic statements. It only treats things as 1 (true) or 0 
(false). What this means is this; :If 1 will ALWAYS be true and the 
calc will ALWAYS execute the next line, or If 0 will ALWAYS be false 
and the calc will NEVER execute the next line. Using the same logic, 
if you wanted a line to be; If N<>0, then you could also just put; If 
N. Because an and statement requires BOTH to be true, it is the same 
as multiplication. ie. If A<>0 and B<>0  is the same as If AB. For a 
much better explaination I recommend going to the TI-Philes BASIC 
columns and reading the 3 articles titled "Advanced TI-82 Programming" 
by Frank Force. VERY good explaination.
