Once you enter the interrupt routine (at org 0x004), you simply poll all the
interrupt flag bits for the interrupts that you have enabled.  Don't forget
to CLEAR the appropriate flag bits before you issue a RETFIE command!

e.g.

  ORG 0x004

  btfsc INTCON, INTF  ; check for RB0 interrupt
  goto INTF_SET  ; RB0 interrupt has occurred
  btfsc INTCON, T0IF  ; check for TMR0 overflow
  goto TMR0_SET  ; TMR0 overflow has occurred

INTF_SET
  bcf INTCON, INTF  ; clear the flag bit first
.
.
.
  retfie

TMR0_SET
  bcf INTCON, T0IF  ; clear the flag bit first
.
.
.
  retfie
