picaxe readtemp function equivalent in picbasic

Hi,
This may be a completely retarded question but i have very little experience with picbasic and picaxe for that matter.
I'm working on a project and i've got a code i've written in picaxe. I've used the readtemp command but i'm unsure how i would use this in the picbasic logic.
Is there an equivalent term to use, my programming is pretty much just comparing two temperature sources (both DS18S20's) and checking for a varience between the two, then turning on an output when the difference is great enough.
Thanks in advance

These should get you going

Sorry I'm still not really grasping the concept;
my current code looks simular to this

in picaxe
readtemp 0, b0 'storage cell 1 temp
readtemp 1, b1 'storage cell 2 temp

start:
let b0=b0+30 'simulate 30 degree celcius offset
if b0>b1 then 'check if storage cell 1 is more than cell 2
high 3 'open solenoid to transfer
endif
let b0=b0-30 'return b0 to true reading

in picbasic ive written it roughly like this but unsure how to do the readtemp part or i'm possibly completely wrong all together?
trisb.0=1
trisb.1=1

cell1temp var portb.0
cell2temp var portb.1
solenoid var portb.3
start:
let cell1temp = cell1temp +30
if cell1temp > cell2temp then
high solenoid
endif
let cell1temp = cell1temp - 30

Pretty much forget the picaxe stuff. It does not look like picaxe is comparable with PBP.

Follow the example I linked to for one-wire devices. Bruce gives the best explanation I know of.

MiskaA...

Here is another example on how to read the DS18B20 temp sensor... or several of them. This example is based on the same code that Mackrackit linked to.

Thanks for the links, it's has given me some more insight into what i'm trying to acheive.
I'm actually using a pic16f684 and have connected the "DQ" pins of the temp sensors to their own pins on the pic chip (pins 6 & 7) so i don't think i need to identify them via a 1 cable network?
Could i just use something like;

trisc.4 = 1
trisc.3=1
cell1 VAR PortC.4 ' One-wire data pin "cell1" on PortC.4
cell2 VAR PortC.3 ' One-wire data pin "cell2" on PortC.3
solenoid VAR PORTC.1 'solenoid contactor coil power

Cold_Bit VAR R_Temp.Bit11' Sign-Bit for +/- Temp. 1 = Below 0 deg C
Real_Cold CON 1 ' Define Real_Cold = 1
R_Temp VAR WORD ' RAW Temperature readings
TempCell1c VAR WORD ' Temp in deg C
TempCell2c VAR WORD ' Temp in deg C

start:
GOSUB Temp_1
GOSUB Temp_2
let tempcell1c = tempcell1c + 21
if tempcell1c > tempcell2c then
high solenoid
else
low solenoid
end if
let tempcell1c = tempcell1c - 21
pause 45000
goto start
