I have an 8 bit binary value in a register and would like to turn this in
to three digits of ascii for output on a LED display.

I am using a 16c74.

I have found one possible soulution on a PIC FAQ but do not  understand
the command 'BNC'

Here is the code.

-----------------------------------------------------------------------
   LIST    R=DEC

          ASCIIO  EQU     ....    ;A FILE REGISTER.
          ASCIIT  EQU     ....    ;ANOTHER FILE REGISTER.
          ASCIIH  EQU     ....    ;ANOTHER FILE REGISTER.

     ; ENTER WITH ORIGINAL 8-BIT VALUE IN "ASCIIO".  EXITS WITH ASCII
     ; REPRESENTATION OF ONES' DIGIT IN "ASCIIO", TENS' DIGIT IN
"ASCIIT",
     ; AND HUNDREDS' DIGIT IN "ASCIIH".

     CONVRT  MOVLW   '0'
             MOVWF   ASCIIH
             MOVWF   ASCIIT

     DO100S  MOVLW   100
             SUBWF   ASCIIO,W
             BNC     DO10S

             MOVWF   ASCIIO
             INCF    ASCIIH
             GOTO    DO100S

     DO10S   MOVLW   10
             SUBWF   ASCIIO,W
             BNC     ADJUST

             MOVWF   ASCIIO
             INCF    ASCIIT
             GOTO    DO10S

     ADJUST  MOVLW   '0'
             ADDWF   ASCIIO

If this code is incorrect please let me know.
If you know how to solve my problem your help would be much appreciated.
