Making Decisions with IF-THEN
10 INPUT "ENTER A NUMBER";N 20 IF N > 100 THEN PRINT "THAT IS A BIG NUMBER!" 30 IF N < 100 THEN PRINT "THAT IS A SMALL NUMBER" 40 IF N = 100 THEN PRINT "EXACTLY 100!"
Loops with FOR-NEXT
10 FOR I = 1 TO 10 20 PRINT I; " COMMODORE 64 IS GREAT!" 30 NEXT I
Pro Tip: Use line numbers in increments of 10. This leaves room to insert lines later (15, 16, 17...)
