I have installed the latest DT_INT files but my following code is giving problem.
Without any variable declaration, it is showing out of memory....
Code:
Include "modedefs.bas"
INCLUDE "DT_INTS-14.bas"     ; Base Interrupt System
INCLUDE "ReEnterPBP.bas"     ; Include if using PBP interrupts
DEFINE     NO_CLRWDT    1

@ __Config _LP_OSC & _WDT_OFF & _PWRTE_ON & _MCLRE_OFF & _BODEN & _CP & _CPD
