Hey all,

I am trying to make a program that uses an LCD display.  I know the
LCD works fine, but I want to send a long string of text.  Instead of
doing each letter individually, I tryed to construct a jump table with
dt.  However, debugging shows that W always contains 8 after the jump
table, instead of the ascii code for the correct letter.

Heres a <snip> of my code:

getstring
	addwf	PCL,f   ; A subroutine to fetch a letter
	dt	"olleH"    ; (hello backwards

<snip>

; meanwhile, in the main program......

                 movlw 04h                   ; number of characters
                 movwf number              ; character counter

loop:          movf number,w             ; put in in W
                 call getstring               ; put character number W into W
                 IOExpLCDSendData    ; macro which sends the data in W

                 decfsz number,f
                 goto loop

<snip>

BTW, I know there are ways of sending a string the right way around,
but I find it easier to just reverse the string in the dt, and run the
loop decrementing.

Thanks in advance,
