The information in this article applies to:

  • Microsoft Macro Assembler for MS-DOS, version 6.0
  • Microsoft Macro Assembler for OS/2, version 6.0

SYMPTOMS

The Microsoft Macro Assembler (MASM) version 6.0 may incorrectly generate the following error when using a user-defined prologue 

   error A2114: INVOKE argument type mismatch : argument: x
(where x is an argument number). The sample code below produces the following errors when assembling: 

   error A2114: INVOKE argument type mismatch : argument : 2
   error A2114: INVOKE argument type mismatch : argument : 1
This error occurs only if an INVOKE directive immediately follows a PROC statement.

RESOLUTION

If an executable statement or a label is placed between the PROC statement and the INVOKE statement, the error does not occur. In the sample code below, uncommenting the line preceding the invoke will cause the assembler to generate a local label and the code will assemble properly.

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 following sample code can be used to demonstrate the problem.
