Im using win32a.inc in my code and had single function that needed wide characters so I put together the following macro to toggle TCHAR before the stdcall. This below works but I initially wanted it to be able to check if TCHAR as already wide but couldnt figure out how to do a restore here. I got confused when I found TCHAR was defined as both a struc and a macro. How does the label work in this situation? Any help is appreciated. Thanks!

Code:
macro stdcallw? allargs&
        struc? TCHAR args:?&
                . du args
        end struc
        macro TCHAR args:?&
                du args
        end macro

        stdcall allargs

        struc? TCHAR args:?&
                . db args
        end struc
        macro TCHAR args:?&
                db args
        end macro
end macro

macro invokew?: proc*,args&
        stdcallw [proc],args
end macro

For a general answer to your main question see section about symbol classes in the manual.

If the first identifier in the line is a known macro, the second one is not considered. Therefore labeled macro (the one defined with STRUC) is only recognized when it follows a name that is not a known instruction/macro.

As for restoring the macros to their previous state, you should simply use PURGE and RESTRUC (for MACRO and STRUC respectively):
Code:
macro stdcallw? allargs&
        struc? TCHAR args:?&
                . du args
        end struc
        macro TCHAR args:?&
                du args
        end macro

        stdcall allargs

        restruc TCHAR
        purge TCHAR
end macro
