Delimiting thousandths..converting 12345678 to 12, 345, 678 for example

If you just need something for whole integers, how about something  
simple like:

function thousandsDelimit pNum
   	repeat with i=-1 down to (0 - length(pNum))
     		put char i of pNum before temp
     		if (i mod 3 = 0) then put comma before temp
   	end repeat
  	if (char 1 of temp is comma) then delete char 1 of temp
   	return temp
end thousandsDelimit

If you needed to work with decimals, you could call it with something  

set the itemDelimiter to "."
put thousandsDelimit(item 1 of tNum) into item 1 of tNum
