pullup and pulldown resistor help

[Archangel]

I think I am following you but want to make sure. Could you expand with an example? THanks

ok

If PortA.1 = 1 THEN ' if logic high = true use pulldown to 
                    'make untrue
Do something here !
else ' false this is where the pulldown does it's work.

If PortA.1 = 0 THEN ' If logic low is true use a pullup to
                    ' make false
 Do something here !Light an LED . . .
else ' False, again this is where pullup does it's job
Your code here . . . Say, turn off the LED
