See section 4.29 in the manual "Standard I/O functions and serial I/O". PAge
96 in my copy.

You need to read the chip documentation for this. Look up the CONFIG register
bits in the Microchip data sheet, and put these in. For example,

__CONFIG(0x3FB1);

would set code protection off, ICD off, flash memory write enabled,
data EEPROM write enabled, low voltage programming enabled, brown out
reset disabled, power up timer enabled, watchdog disabled, and XT oscillator.

To learn a language, you need to remove as many difficulties as possible. You
are far better to learn C programming before you try to program a PIC in C.
You need to be able to walk before you can run.
