    You must use MPASM with DT's interrupts.
    Then you will need to use MPASM type configs

    No problem.

    Try changing the config line to
    @ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _LVP_OFF & _CP_OFF
    and make sure the *.inc file is commented.
    Then add
    wsave VAR BYTE $70 SYSTEM
    in your VAR section

    Take a look at this
    http://www.picbasic.co.uk/forum/show...=6775#post6775
    When the configs are set in code space the *.inc file needs the config lines commented.
