The information in this article applies to:
- Microsoft Macro Assembler (MASM), version 6.11
-------------------------------------------------------------------------------
SYMPTOMS
========
The assembler uses the DGROUP symbol to load the DS register with a data segment
value in the prolog code, even in a flat-model program. This causes the
assembler to generate "error A2006: Undefined symbol: DGROUP" because groups are
not supported in flat-model code.
This behavior is demonstrated through the following procedure definition and
generated prolog code, both from the listing file:
MyProc proc <loadds> word_val:WORD
; push bp
; mov bp, sp
; push ds
; mov ax, DGROUP
; mov ds, ax
ret
MyProc endp
RESOLUTION
==========
To work around the problem, take out the <loadds> when building in flat
model.
STATUS
======
Microsoft has confirmed this to be a bug in MASM version 6.11. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
