Thanks Edward, but there is still something that seems unclear to me. You are calling this a subroutine, but there seems to be no method of passing a variable into it. It looks like it will print "EYE DLY " when called. Could you elaborate a little about passing a string into the subroutine? I've gotten pretty lazy over the years and I'm very much used to setting up some human terminology in my lcd calls like this:
*************
Line1 CON 128
Line2 CON $c0
clr CON 1
I CON $FE
*************

I then pass the values out in simple human language terms as follows:
***************
lcdout I,clr 'clear the LCD
lcdout I,Line1, "Ion current"
lcdout I,Line2,#valu dig 2,".",#valu dig 1,#valu dig 0,"e-0",#scale 'scientific notation display of current reading.

***************
I realize that you are no longer using lcdout, but your own routine instead but I'm still missing something.

Thanks,
John.
