'Retrieving' is a job for a PIC programmer I would say.

I use it in a PIC program as follows:
At the end of a program I define a fuction like this:

#pragma origin 0x3ff
static char  calibrate(void) {
   return 128;  // dummy! value.
   }

And in main() I call this function as follows:

  OSCCAL = calibrate();

Of course in a similar way you can use the returnvalue of calibrate()
for other purposes.

BTW You have to have a programmer that supports the 16F629/675 and
preserves the last word of program memory. It must ignore the contents
of the hex file occupied by the function calibrate()!

Regards, Rob.
