Andre,

Found these in your file:

                list p=16c74A
                #include        c:\mplab\p16c74A.inc

If you "are" using a PIC74, maybe try changing the following lines:

                BCF     ADCON0,ADIF     ; RESET A/D INIT FLAG (ADIF)
LOOP            BTFSC   ADCON0,ADIF     ; A/D OVER ?
                BTFSS   ADCON0,ADIF     ; A/D INTERUUPT
                BSF     INTCON,ADIE             ; ENABLE A/D INIT

to these:

                BCF     pir1,ADIF     ; RESET A/D INIT FLAG (ADIF)
LOOP            BTFSC   pir1,ADIF     ; A/D OVER ?
                BTFSS   pir1,ADIF     ; A/D INTERUUPT
                BSF     pie1,ADIE             ; ENABLE A/D INIT

also, check that you are re-initializing everything after this instr:

                CLRF    INTCON                  ; CLEAR ALL INTERRUPTS

also, is this a defined variable, or do you really mean < pir1 >?

UPDATE:         BCF     ADIF,6          ; RESET SOFTWARE A/D FLAG
