how about starting local name with "."?
Code: proc a local .loc endp proc b local .loc endp |

Hi vid!
It is not needed, the following works fine, but i don't catch implementation Code: struct ASD A dd ? B dd ? C db ? ends proc A local str : ASD mov eax,[str.A] ret endp proc B local a : DWORD local str : ASD mov eax,[str.B] ret endp stdcall A stdcall B Regards. _________________ Flat Assembler is the best! |

The implementation abstract:
Code: A: ; proc A virtual at ebp-4 ..a?0001 dd ? a equ ..a?0001 end virtual mov eax,[a] ret restore a ; endp B: ; proc B virtual at ebp-4 ..a?0002 dd ? a equ ..a?0002 end virtual mov eax,[a] ret restore a ; endp |

Of course it is the obvious decision, but i have made some experiments with your macro package and left only nessesary part. Please explain how it works:
Code: macro deflocal@proc name,def,val { local ..var ..var def val name equ ..var } macro do_local Name,Type,Pos { virtual at Pos macro label . ; <- why label is redefined? \{ deflocal@proc .,:, ; <- why it must be done with macro here? \} Name Type end virtual } struct ASD a dd ? b dd ? ends A: do_local a,ASD,esp+4 retn restore a B: do_local b,dd,esp+4 do_local c,ASD,esp+8 retn restore b Thanks and regards. _________________ Flat Assembler is the best! |

This is done this way so the structures can be put inside locals. The "struct" macro always defined main structure label with the "label" directive, so by re-defining the "label" here you can adjust that definition to your own.
Note that this means that "local" macro will work correctly with structures only if they were defined with official "struct" macro (from the same includes package). |

Hi, Tomasz!
Please explain, why i got 'symbol already defined' error in this case? Code: macro deflocal@proc name,def,val { local ..var ..var def val name equ ..var } macro do_local Name,Type,Pos { virtual at Pos macro label . \{ deflocal@proc .,:, \} Name Type purge label end virtual } struct ASD a dd ? b dd ? ends A: do_local a,ASD,esp+4 retn restore a B: do_local a,ASD,esp+8 retn restore a Thanks and regards. _________________ Flat Assembler is the best! |

You did not restore the names for all the fields (including "a.a").

But this doesn't work too. Maybe some other implementation needed to restore the values?
Code: macro deflocal@proc name,def,val { local ..var ..var def val name equ ..var } macro do_local Name,Type,Pos { virtual at Pos macro label . \{ deflocal@proc .,:, \} Name Type purge label end virtual } struct ASD a dd ? b dd ? ends A: do_local a,ASD,esp+4 retn restore a restore a.a restore a.b B: do_local a,ASD,esp+8 retn restore a Thanks and regards. _________________ Flat Assembler is the best! |

Oh, right, you also did not redefine "dd" to use deflocal@proc.
