 Last reviewed: November 3, 1994
Article ID: Q34503
The information in this article applies to:
  • Microsoft Macro Assembler for MS-DOS and OS/2, version 5.1

SUMMARY

Page 38 of the "Microsoft Macro Assembler 5.1 Update" guide states the following about the type that can be specified for an argument in the syntax of PROC 

   ... the type of the argument may be WORD, DWORD, FWORD, QWORD,
   TBYTE or the name of a structure defined by a STRUC structure
   declaration...
When attempting to use a structure name, the following error will be generated 

   error A2003: Unknown type specifier
The error is generated because support of the STRUC type for arguments to PROC has not been added to MASM version 5.1. However, it is a feature of MASM version 6.0 and later.

MORE INFORMATION

The following program illustrates the problem. It will assemble correctly with MASM 6.0 and later.

Sample Code

; Assembly options needed: none 

   .model small,c
   .data
t1 STRUC 
   w1  dw 0
t1 ENDS 

   .code
h1 PROC arg1:t1 ; h1 ENDP 

   END
