<p><b>Return:</b><br>ES:DI -> FAR procedure to fetch error message
09h set ??? error table

</PRE>
<p><b>Notes:</b>
If the returned segment on a "get" is 0001h, then the offset specifies
the offset of the error message table within COMMAND.COM, and the
procedure returned by DL=08h should be called.
DOS 5+ COMMAND.COM does not allow setting any of the addresses (calls
with DL odd are ignored); they are always returned with segment 0001h.
For DOS 5.0, the standard and critical/SHARE error tables are combined
into a single error table

Format of DOS 4.x error table:
<a name=table2614></a>
Offset Size Description (Table 02614)
00h BYTE FFh
01h 2 BYTEs 04h,00h (DOS version???)
03h BYTE number of error headers following
04h 2N WORDs table of all error headers for table
Offset Size Description
00h WORD error message number
02h WORD offset of error message from start of header
error messages are count byte followed by msg
</PRE>
<p><b>Note:</b>
DOS 5 error tables consist of one word per error number; each word
contains either the offset of a counted string or 0000h
<PRE>
<p>
<a name=table2615></a>
(Table 02615)
Call error retrieval function with:.
AX = error number <a href="rb-4414.htm#Table2616" tppabs="http://www.ctyme.com/intr/rb-4414.htm#Table2616">(see #02616)</a>.
DI = offset of error table<br>
<p><b>Return:</b><br>ES:DI -> error message (counted string)
</PRE>
<p><b>Notes:</b>
This function needs to access COMMAND.COM if the messages were not
loaded into memory permanently with /MSG; the caller should assume
that the returned message will be overwritten by the next call of
the function.
Supported by DR DOS 5.0
