Problem Programming 16F870 when adding ON INTERRUPT

[dream-]

Intcon.5 = 1 'enable tmr0

Unfortunately this didn't do anything

I just tested this code on a 16F870 and a 16F628A:

led     var     PORTB.7


        OPTION_REG = $7f        ' Enable PORTB pullups

        On Interrupt Goto myint ' Define interrupt handler
        INTCON = $90            ' Enable INTE interrupt

loop:   High led                ' Turn LED on
        Goto loop               ' Do it forever


' Interrupt handler
        Disable                 ' No interrupts past this point
myint:  Low led                 ' If we get here, turn LED off
        Pause   500             ' Wait .5 seconds
        INTCON.1 = 0            ' Clear interrupt flag
        Resume                  ' Return to main program
        Enable

I get the error in the PROGRAMMER in both cases. The error is in the code verification stage.

Why would the programmer give this type of error, as if the code was not being written properly to the PIC? If I remove the "ON INTERRUPT" line, the code saves perfectly. I have been using this programmer for a while and had no problems until this one.

Is the PICBASIC compiler inserting code in a non-programable area or something?
