Thanks, thats a great help although I had actually seen it when I was doing some research for this, what I dont get is how you use it as a thermostat though, monitoring a certain range of temperatures.
I'm using the 16f877 and the DS18B20 because thats what I have handy at the moment.

I was actually just reading that at the same time you typed that.
it looks extremely promising, although not having used the serout command or serial at all yet it "seems" a bit complex but I'm assuming I can just change the serout commands to lcdout and pick the line i want it displayed.
It's late at the moment and I'll look again tomorrow when I'm fresher, but at a glance I cant see past of that code that compares the range of temperatures and acts on it,(thermostat range) although as I said its late and Im tired so I'm probably missing it.
Thanks for the help so far guys, it's nice being able to pick people's brains and sorry if I seem to be making mistakes and missing things at the moment.

Are you asking how to use the information gathered from the DS18B20 ?
something like:

loop:
IF MYVAR1 >=  75 THEN
 PortB.1 = 1
IF MYVAR2 <=  65 THEN
 PortB.0 = 1
else
portb.1 = 0
portB.0 = 0
serout PortB.6,N9600,[254,128,"Inside temp is,"#myvar1]
serout PortB.6,N9600,[254,192,"Outside temp is,"#myvar2]
endif
endif
goto loop
