*********************************************************************************************************
* SAVE DOS RETURN LOCATION
*
* Description : This function saves the location of where we are in DOS so that it can be recovered.
* This allows us to abort multitasking under uC/OS-II and return back to DOS as if we had
* never left. When this function is called by 'main()', it sets 'PC_ExitFlag' to FALSE
* so that we don't take the 'if' branch. Instead, the CPU registers are saved in the
* long jump buffer 'PC_JumpBuf' and we simply return to the caller. If a 'long jump' is
* performed using the jump buffer then, execution would resume at the 'if' statement and
* this time, if 'PC_ExitFlag' is set to TRUE then we would execute the 'if' statements and
* restore the DOS environment.
*
* Arguments : None
*
* Returns : None
