INT 2F - DOS 3.3+ internal - MOVE FILE POINTER

	AX = 1228h
	BP = 4200h, 4201h, 4202h (see INT 21/AH=42h)
	BX = file handle
	CX:DX = offset in bytes
	SS = DOS DS (must be using a DOS internal stack)
Return: as for INT 21/AH=42h
Notes:	equivalent to INT 21/AH=42h, but may only be called from inside a DOS
	  function call
	sets user stack frame pointer to dummy buffer, moves BP to AX, performs
	  LSEEK, and restores frame pointer
	used by NLSFUNC to access COUNTRY.SYS when invoked by the DOS kernel
