    PORTA.6 and PORTA.7 on the 16F819 are the oscillator pins. I assume therefore that you are using the internal oscillator. If so, you need to make sure the config bits for the oscillator are set to _INTRC_IO (assuming you are using PMASM as your assembler).

    Greetings Kamikaze47,

    Thanks for your reply

    Yes I am using internal oscillator.

    I don't know How set config bits in _INTRC_IO, Can you let me know, How I make this from PicBasic Pro?

    Thanks in advance

    OK,
    I aded @ __config _INTRC_OSC_NOCLKOUT to set the PIC for Internal Oscillator allowing
    use of the OSC pins as I/O, but when I compile, the error 44 : symbol not previously defined
    appear.

    Any suggestion?

    thanks,
