16f886 interrupt on portB problem

[sougata]

INTCON = %10001000 '%10001000 port b int on change and global interrupt enable
'bit 7 = GIE: Global Interrupt Enable bit
'bit 6 = PEIE: Peripheral Interrupt Enable bit
'bit 5 = T0IE: Timer0 Overflow Interrupt Enable bit
'bit 4 = INTE: INT External Interrupt Enable bit
'bit 3 = RBIE: PORTB Change Interrupt Enable bit(1)
'bit 2 = T0IF: Timer0 Overflow Interrupt Flag bit(2)
'bit 1 = INTF: INT External Interrupt Flag bit
'bit 0 = RBIF: PORTB Change Interrupt Flag bit
IOCB.0=0 'ENABLE INERRUPT ON CHANGE PIN ON PORT B (W3)
IOCB.4=0 'ENABLE INERRUPT ON CHANGE PIN ON PORT B (W1)
IOCB.5=0 'ENABLE INERRUPT ON CHANGE PIN ON PORT B (E3)
IOCB.6=0 'ENABLE INERRUPT ON CHANGE PIN ON PORT B (E2)
IOCB.7=0 'ENABLE INERRUPT ON CHANGE PIN ON PORT B (E1)

Is it my head ????

Thanks Bruce for pointing out (Not that I am getting dumber)........ the IOCB bits
