    I'm new to microprocessors and MPLab. I've been instructed to change value of the bit from 3FFF to 3F73 however, I'm unable to erase or change the 3FFF. I high lighted it, but still it won't allow me to change it. What's my problem?

    You need to be more specific. Are you referring to being in debugging mode with a microcontroller in MPLab? Where is this value at? In RAM? Program memory?

    Help us help you...

    You can either do it by putting the line:
    __config 0x3F73
    after the include line near the top of the assembly code (there are two underscore characters before config).

    Or do it in a much more readable way like:
    __config _LVP_OFF & _BOREN_OFF & _PWRTE_ON and _WDT_OFF & _HS_OSC
    (these settings are almost certainly wrong, I couldn't be bothered to work out what 3F73 translates to).
