[Isis-users] Former command "lr"

[spinaker]

Dear Victor

You are right (in part) ...
Because of this limitation (there is no "LR" code) Guilda implemented a 
solution
Please, take a look in
http://abcdwiki.net/wiki/es/index.php?title=Formatos_de_salida_que_integran_la_informaci%C3%B3n_de_bases_de_datos_relacionadas
Formatos de salida que integran la información de bases de datos 
relacionadas

/" ... Ahora bien, según establece la teoría, la función L recupera solo 
el mfn del primer registro localizado a través de la expresión de 
búsqueda suministrada, y en la relación entre la base bibliográfica y 
sus copias tenemos que un registro bibliográfico puede relacionarse con 
varios registros en la base de datos de copias.

  Ante esta situación, ABCD generó su propia forma de acceso a las 
relaciones de este tipo, incluyendo en la pft, como preliteral 
incondicional, el siguiente comando:
          /'$$REF:Base_de_datos, Formato, Expresion de búsqueda'/
/
etc

Regards
Ernesto Spinak
