To know which Int to use, you need to be a bit of a sleuth, the same thread...

I think you need to open dts_int-14.bas, do a search within for RABC, you should see these entries...

Code:
  #define RAC_INT      INTCON,RAIF,  INTCON,RAIE   ;-- RA Port Change      *
  #define RBC_INT      INTCON,RBIF,  INTCON,RBIE  ;-- RB Port Change
  #define RABC_INT     INTCON,RABIF, INTCON,RABIE  ;-- RAB Port Change

....see which one of those bolded registers a 16f690 actually has & then use the associated DTS Int. (eg search the data sheet for RAIF...nothing, RBIF...nothing, RABIE ...bingo ...so use the RABC_INT)
