BUG: ML Uses DGROUP in Flat Model and Generates A2006 (120066)
The information in this article applies to:
- Microsoft Macro Assembler (MASM) 6.11
This article was previously published under Q120066 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.
