Doubt with interrupt on change

Well my problem is that i want to make an interrupt on change with RA0 on PIC16F684 but since i'm beginer in this and i'm not a well english reader i have troubles doing this, mi code next:

[B]inicio:
if INTCON.0 = 0 THEN disparo
GOTO inicio

disparo:
PORTA.0 = 1
INTCON.0 = 0
FREQOUT PORTC.5,10,38000
PORTC.5 = 0
RONDAS = RONDAS - 1
GOTO inicio[\B]

if somebody can help me, i'd be very glad. Thanks

Hi lugo.p,
Let's start off with, change the big old Capital B to the word code, then your code tag will work, do it on both ends.

Add this to your code along with the proper configs and define your OSC.

Code:

---

ON INTERRUPT GoTo disparo
INTCON = %10001001
'Bit 0 = RAIF      Port A Interrupt Flag
'Bit 1 = INTF      INT Flag
'Bit 2 = T0IF      Timer zero Interrupt Flag
'Bit 3 = RAIE      Port A Interrupt ENABLE
'Bit 4 = INTE      INT Enable
'Bit 5 = T0IE      Timer zero Interrupt Enable
'Bit 6 = PEIE      Peripheral Interrupt Enable
'Bit 7 = GIE      Global Interrupt Enable

IOCA = %00000001  ' enable IOC on RA0
'Bit 0 = RA0 interrupt on change
'Bit 1 = RA1  "  "    "  " "
'Bit 2 = RA2  "  "    "  " "
'Bit 3 = RA3  "  "    "  " "
'Bit 4 = RA4  "  "    "  " "
'Bit 5 = RA5  "  "    "  " "
'Bit 6 = Unimplemented
'Bit 7 = Unimplemented

OPTION_REG = %00000000
'Bit 0 = PS    Prescaler
'Bit 1 = PS    Prescaler
'Bit 2 = PS    Prescaler
'Bit 3 = PSA    Prescaler Assignment bit
'Bit 4 = T0SE  Timer zero source edge select bit
'Bit 5 = T0CS  Timer zero clock source select bit
'Bit 6 = INTEDG Interrupt Edge Select bit
'Bit 7 = RAPU  PortA weak pullup bit

---

And puting that on my code IOC will work?

Because i have configured IOCA = $01, OPTION_REG = $00 and INTCON = $98
