Before using the Program Library
• Be sure to check how many bytes of unused memory is remain-
ing before attempting to perform any programming.
• This Program Library is divided into two sections: a numeric cal-
culation section and a graphics section. Programs in the numeric
calculation section produce results only, while graphics programs
use the entire display area for graphing. Also note that calcula-
tions within graphics programs do not use the multiplication sign
( ) wherever it can be dropped (i.e. in front of open parenthesis).

    PROGRAM SHEET Program for Prime Factor Analysis Description Produces prime factors of arbitrary positive integers For 1 < < 10 Prime numbers are produced from the lowest value first. “END” is displayed at the end of the program. (Overview) is divided by 2 and by all successive odd numbers ( = 3, 5, 7, 9, 11, 13, ..) to check for divisibility.
