button help

[Archangel]

gee, that example is confusing. all i want to use is 5 buttons on port c of my 16f873.

button A = High Setpoint
buttonB = Low Setpoint
buttonC= Increment
buttonD= Decrement
buttonE= Return to main display

At power up of my device, I want my program to prompt the user to enter a high and low setpoint then continue to display the main program afterwards. If the user decides to change setpoint, then the buttons above can be used.

Yes, it can be so why bother with all that keypad code then?

'simple if then loop
BUTTONA VAR PORTC.0
BUTTONB VAR PORTC.1
BUTTONC VAR PORTC.2 ' and so on . . . 
MAIN:
IF BUTTONA = 0 THEN gosub High_Setpoint
IF BUTTONB = 0 THEN GOSUB Low_Setpoint
IF BUTTONC = 0 THEN GOSUB Increment
' More code goes in here

GOTO MAIN
high_setpoint:
'do something in here
return
Low_Setpoint:
'do something in here
return
Increment:
'do something in here
return

'more sub directories here


end
