You use these to label certain parts of your program. Then, you use the Goto command to go to these labels. It works like this: Lbl MM :Input "1,2?",A :If A=1 :Goto EF :If A=2 :Goto YU :Lbl EF :Disp "You entered 1" :Stop :Lbl YU :Disp "You entered 2" :Pause :Goto MM The "Stop" command forces the program to stop. You can get this by going to [PRGM] {F}. You can have more than one goto going to a single Lbl. Work with this a little bit. We usually put a label at the very beginning of the program called ST, for start, and one right above the main menu, called MM. Labels can only be 2 characters long, and they can only be uppercase letters or numbers. |
