Hi to all the prof. here...
I am adding a serial send routine to my existing code in PIC assembly.
I am using PIC 16F88 with MPLAB version 8.10.00.00


However when i compile my file, i get this error:

Code: 
Warning[207] D:\WATT METER (DESIRED DESIGN)\WATTMETER.ASM 1480 : Found label after column 1. (settle)
[B][COLOR="Red"]Error[113]   D:\WATT METER (DESIRED DESIGN)\WATTMETER.ASM 1488 : Symbol not previously defined (Send)
Error[113]   D:\WATT METER (DESIRED DESIGN)\WATTMETER.ASM 1490 : Symbol not previously defined (Send)[/COLOR][/B]

The post below is the file I am implementing. Red highlighted part is the one i added for send serial routine. Thanks. I wonder what silly mistakes i had done.

   btfss       TXSTA, TRMT         ; Loop until data is sent
   goto      trans_wt      
   return

If you ask, MPLAB can be case sensitive, just change your label send to Send, and the problem should disappear.
 
Like this?

The problem still exists:

Code: 
call 	Serial_Sent

Serial_Sent:
   banksel      SPBRG
   movlw      .25                  ; 9.6kbps
   movwf      SPBRG
   movlw      b'00100100'      ; brgh = high (2)
   movwf      TXSTA            ; enable Async Transmission, set brgh

   ; Provide a settling time for startup
   banksel      tmp1
   clrf       tmp1
   settle
   decfsz       tmp1, f
   goto       settle


   ; Send a character through the UART
loop
   movf AmpHours, w
   call Send
   movf AmpHours+1, w
   call Send
   goto      $
 
Code: 
loop
   movf AmpHours, w
   call Send   ;error here
   movf AmpHours+1, w
   call Send   ;error here
   goto      $

;----------------------
; SEND function
;----------------------
[B][U][size=+1][color=red]S[/color][/size][/U][/B]end
   banksel      TXREG
   movwf       TXREG            ; Send data which has been stored in W
