Summary:

PROBLEM ID: MSM9109001

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

CAUSE

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.

Microsoft has confirmed this to be a problem in MASM version 6.0.

This problem was corrected in MASM version 6.0a.
