Article: Q26839
Product(s): Microsoft Macro Assembler
Version(s): 5.0,5.1,5.1a
Operating System(s): 
Keyword(s): 
Last Modified: 06-MAY-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Macro Assembler (MASM), versions 5.0, 5.1, 5.1a 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Microsoft Macro Assembler will generate a misleading error message when a
segment with the AT combine type is specified with a segment value that is too
large. The error message generated will be:

  error A2029: Division by 0 or overflow

It is not clear from the error message that the segment value was too large.

CAUSE
=====

This is the expected behavior of MASM 5.0, 5.1, and 5.1a.

RESOLUTION
==========

MASM 6.0 now generates the following error message:

  error A2084: constant value too large

MORE INFORMATION
================

The following sample code can be used to demonstrate the problem.

Sample Code
-----------

  ; Assemble options needed: none

  S1  SEGMENT AT  01234H   ; This segment is OK
  S2  ENDS

  S2  SEGMENT AT  12345H   ; This segment generates a misleading error
  S2  ENDS

  END
