I have finally understood and realized how the locals ... endl macros work for primitive (db , dw & dd) types...

I have been able to re-create these forms inside my macros - I am trying to create an OO library (inheritance, polymorphism and COM), with err treatment (for Win32) - but I still have the problem of working with structures...

I tried using the macro label . definition, but everytime I use an structure it places a global label (without the '.' ) .

                        \macro locals
                                match t_strStack , STACKFRAMETYPE
                                        StartLocalData a_strClass , a_strProc , t_strStack
                                        macro label . \\\\{ deflocal a_strClass , a_strProc, t_strStack ,  . , : , \\\\}
                                        struc dd [val] \\\\{ \\\\common deflocal a_strClass , a_strProc , t_strStack , . , dd , val \\\\}                               
                                        struc dw [val] \\\\{ \\\\common deflocal a_strClass , a_strProc , t_strStack , . , dw , val \\\\}                               
                                        struc db [val] \\\\{ \\\\common deflocal a_strClass , a_strProc , t_strStack , . , db , val \\\\}                               
                        \macro endl
                                purge label
                                restruc dd
                                restruc dw
                                restruc db
                                match t_strStack , STACKFRAMETYPE \\\{ EndLocalData a_strClass , a_strProc , t_strStack \\\}

macro deflocal a_strClass , a_strProc , a_strStack , a_strAddress , a_strSize , [a_astrData]

        match x , LocalDataList \{ LocalDataList equ LocalDataList, \}
        LocalDataList equ LocalDataList a_strAddress
        local ..var
        ..var a_strSize a_astrData

        match =EBP x , a_strStack ..var \{ a_strAddress equ [ebp - LOCALSIZE + x] \}

        match =ESP x , a_strStack ..var \{ a_strAddress equ [esp + x] \}

The main thing is that I am trying not only to put it working, but I am also trying to understand all the mechanics involved. That is why I am re-writing the macros.

I appreciate any help.

If there is someone interested in those libraries after I finish them, I might publish it here. In order to do that, I would like to know how interesting people think this would be.
