Notes about Calling Programs • Variables are global. • label used with Goto and Lbl is local to the program where it is located. label in one program is not recognized by another program. You cannot use Goto to branch to a label in another program. • Return exits a subroutine and returns to the calling program, even if it is encountered within nested loops. Executing a Program The 8 EXEC (execute) menu lists in alphabetical order all created programs. From this list, select the program that you want to execute. The program name is pasted to the cursor location on the Home screen. Pressing b begins executing the program. Pressing b after a program is completed returns you to the Home screen. The 8 EXEC menu labels the first 10 items using 1 though 9, then 0. All other programs are still included in the list, but are not labeled with a number. To select a menu item, press the number associated with it or highlight the item with the cursor keys, and then press b.
