DOS 3.1+ - SET EXTENDED ERROR INFORMATION

AX = 5D0Ah
DS:DX -> 11-word DOS parameter list (see #01686)

Return:
Nothing. next call to AH=59h will return values from fields AX,BX,CX, DX,DI, and ES in corresponding registers

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
