Switch in PIC BASIC HELP!!!!

[BrianT]

Try this idea, it works with PBP in a PIC18F4620 and should work with any PIC that has EEPROM.

I set a byte variable "ProgramState" to 1 in a data statement and write this to EEPROM when the program is loaded into the PIC.

At power up, the code reads the value stored in ProgramState, here set to 1, and jumps to the appropriate code block.

MAIN:
READ 0, ProgramState
If ProgramState = 1 then RunCode1
If ProgramState = 2 then RunCode2
If ProgramState = 3 then RunCode3

If ProgramState > 3 then
write 0, 1 'reset ProgramState to first code block
goto MAIN
endif

RunCode1:
execute codeblock 1
if ButtonDown = 1 then
write 0, 2
endif
goto MAIN

RunCode2:
execute codeblock 2
if ButtonDown = 1 then
write 0, 3
endif
goto MAIN

etc
