APPLIES TO


 * Microsoft Macro Assembler 6.0 Standard Edition

This article was previously published under Q73308



SYMPTOMS
The &quot;Microsoft Macro Assembler Programmer's Guide&quot; that ships with the Microsoft Macro Assembler (MASM) version 6.0 states on page 49 that &quot;options used with the SEGMENT directive can be in any order.&quot; The BNF Grammar for the language also indicates that this should be the case; however, if a class name is specified and it is not the last option listed in a full segment definition, the assembler will generate a syntax error.



RESOLUTION
When using MASM version 6.0, make sure that the class is the last attribute listed.



STATUS
Microsoft has confirmed this to be a problem in MASM version 6.0. This problem was corrected in MASM version 6.0a.



MORE INFORMATION
The sample code below may be used to illustrate this problem. Assembling the code with MASM version 6.0 results in the following errors:

file.asm(1): error A2008: syntax error : word

file.asm(3): fatal error A1010: unmatched block nesting : data

Because MASM 6.0 incorrectly requires a class name to be the last item in a full segment definition, the first error is generated when the assembler fails to recognize the directive option specified after the class name. The second error is merely a side-effect of the first.

Sample Code
; Assemble options needed: none

data   SEGMENT PUBLIC 'DATA' WORD

data   ENDS

END
