Q76078: FIX: Error A2114 When Using OPTION PROLOGUE

Article: Q76078
Product(s): Microsoft Macro Assembler
Version(s): MS-DOS:6.0
Operating System(s):

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

- Microsoft Macro Assembler (MASM), 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.
