Figure 6-1 Example 3–Screen Menu Program
Program 20:
[SCREEN 1] Name the main program
MS1,“ “ Clears keypad screen
MS3,“Select a Part” Writes a Message
MS21,”Part A Part B Part C” Writes a message above function keys
FK1,2,3,17,18 Wait for selected key press
GT(FKEY) Jumps to prog# 1, #2, or #3 if F1,F2, or F3 is pressed Jumps to prog #17, or
#18 if the up or down arrow keys are pressed.
EN End of Routine
Program 18:
[SCREEN 2]
MS21,“Part D Part E Part F” Writes a message above F1, F2, F3.
FK1,2,3,17,18 Wait for selected key press
IF(FKEY)=17 GT[SCREEN 1] EB If Up arrow goto screen 1
IF(FKEY)=18 GT[SCREEN 3] EB If Down arrow goto screen 3 (FKEY)=(FKEY)+3 Add offset to FKEY variable to goto
correct part subroutine.
GT(FKEY) Jumps to part D, E, F in program#4, 5, or 6
EN End of Routine
Program 17:
[SCREEN 3]
MS21,“Part G Part H Part J” Writes a message above function keys.
FK1,2,3,17,18 Wait for selected key press
IF(FKEY)=17 GT[SCREEN 2] EB If Up arrow goto screen 2
IF(FKEY)=18 GT[SCREEN 1] EB If Down arrow goto screen 1
(FKEY)=(FKEY)+6 Add offset to FKEY variable to goto correct part subroutine
GT(FKEY) Jumps to part G, H, J in program #7,8 or 9
EN End of Routine
The programs to make Parts A, B, C, D, etc. are in program numbers 1–9. To continuously cycle through put a
GT[SCREEN 1] at the end of each part program.
