Macro

Notes

Notes:	documented for DOS 5+, but undocumented in earlier versions
the MS-DOS Programmer's Reference incorrectly states that this call was
  introduced in DOS 4, and fails to mention that the ERROR structure
  passed to this function is a DOS parameter list.

BUGS: DR DOS 3.41 and 5.0 read the value for ES from the DS field of the

  DPL; fortunately, MS-DOS ignores the DS field, allowing a generic
  routine which sets both DS and ES fields to the same value
Novell DOS 7 (through at least Update 4) does not save the pointer,
  which is always reported as 0000h:0000h by AH=59h; Update 15 fully
  supports this function
