Originator99,

I'm don't use SX/B, but it looks to me like you're not sending a string, but rather sending an integer to the PC.  You have this code:

[code]      TX_STR temperature       ' send inline string  to PC  ???????????????????????
      TX_STR CrLf              ' send stored z-string
[/code]

The problem is that the definition of "temperature" is this:

[code]temperature  VAR Word                  ' Holds temperature in 0.1°C units (250 = 25.0°C)
[/code]

That is just an integer, and not a string.  Furthermore, temperature is whittled away to crate a string for the LCD, so when it's done, it has nothing or junk in it.  It makes sense that you get junk on the PC side because I am assuming you're using a terminal program to read it.  If so, then the terminal program takes whatever is receives and tries to interpret it as ASCII when it's not - it's a raw integer.

You comment mentions "inline string" but there is no inline string that I see.  Instead, the code creates an  equivalent of the temperature and sends it a character at a time to the LCD as it creates it.  I think that if you follow each call of:

[code]      LCDSend temp
[/code]

with something like:

[code]     temp = temp or $30 'Convert number to ASCII equivalent
     TX_STR temp, 1 'Send to PC[/code]

You should get the results you're looking for.

Bear in mind, I have no idea what hardware you're using.  I'm not sure what LCD you have attached, and if it is working or not.  I also don't know if you have verified that you are able to send [b]any[/b] string data to the PC over a serial port.  If not, then get that working first, and then figure out how to integrate that knowledge into this code you're working on.
