{
  Cria um "MainMenu" via banco de dados automaticamente
  -> Arquivo MENUS.DBF
  Campos -> Campo Character 20 -> Nome do campo
            Sequencia Character 1 -> 1,2,3,...
            Ordem Character 1 -> 1,2,3,...
            Flag Boolean -> .T. ou .F.
            CampoNN Character 20 -> Nome do SubCampo
            FlagNN Boolean -> .T. ou .F.
  -> Índice = ´Sequencia + Ordem´
  Desenvolvido em Clipper/Dbase, função Achoice()
  Convertido para Delphi 7.0 em 20/Agosto/2004
