I'm working on a project using 18LF13K22. I need to use RAB Change Interrupt with DT Ints18. I made changes on DT_INTS-18.bas below but i couldn't succeed. Any suggestion?

Code:
#define RABC_INT  INTCON, RABIF   ;-- RAB Port Change
.........

Code:
ifdef RABIF
      INT_Source  INTCON,RABIF, INTCON, RABIE,INTCON2,RABIP
  endif
Thanks..
