INT 21 - DOS 3.0+ - GET EXTENDED ERROR INFORMATION

	AH = 59h
	BX = 0000h
Return: AX = extended error code (see #01680)
	BH = error class (see #01682)
	BL = recommended action (see #01683)
	CH = error locus (see #01684)
	ES:DI may be pointer (see #01681, #01680)
	CL, DX, SI, BP, and DS destroyed
Notes:	functions available under DOS 2.x map the true DOS 3.0+ error code into
	  one supported under DOS 2.x
	you should call this function to retrieve the true error code when an
	  FCB or DOS 2.x call returns an error
	under DR DOS 5.0, this function does not use any of the DOS-internal
	  stacks and may thus be called at any time
