Thanks for the comments, really appreciate . Ernesto, I was not aware of the $$REF trick, it was good to know. For some reason my web search didn'd get such content from Gilda's wiki. Nice. Egbert, I decided to work another way but 'join' would be fine as well.
I think 'join' would give me the same results under the same limits.<br>

Some institution are willing to search into table of contents. So, they OCR the pages and paste it on MFN (by either traditional ABCD worksheet or a PHP form over IsisScript). The point is, there is a 32kb limitation documented and experienced.</div>

I'm working with table of contents written in text files. Then, I use append method over 1300 table of contents files (such batch is created automatically by PHP), and retag, mxcp, and so on. I have a PHP script that read each table of content file and splits
it if size gets over 32kb. So, I may have something like ID1132A.txt, ID1132B.txt, ID1132C etc, each one under 30kb (there are table of contents with 25 pages or even more, specially in law literature).</div>

Working on a separate database or not, the point is, how to index into the dictionary all the table of contents once we have this 32kb limitation? We are stuck under the formatting language interpreted by mx because there is always need of using a FST. And
unfortunately we can't use $$REF on it. So, we again miss <span><span>'</span></span>LR<span><span>'</span></span> implementation here.</div>

<br>
You are right (in part) ...<br>
Because of this limitation (there is no "LR" code) Guilda implemented a solution<br>
Please, take a look in <br>
<a class="x_moz-txt-link-freetext" href="http://abcdwiki.net/wiki/es/index.php?title=Formatos_de_salida_que_integran_la_informaci%C3%B3n_de_bases_de_datos_relacionadas">http://abcdwiki.net/wiki/es/index.php?title=Formatos_de_salida_que_integran_la_informaci%C3%B3n_de_bases_de_datos_relacionadas</a><br>
Formatos de salida que integran la información de bases de datos relacionadas<br>
<br>
<i><font color="#330099">" ... 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.
<br>
<br>
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:
<br>
/'$$REF:Base_de_datos, Formato, Expresion de búsqueda'/<br>

<p style="margin-top: 0px; margin-bottom: 0px;">you are right : CISIS doesn't have that LR() function and also for me this has created lots of problems. We asked for a quotation to implement this with some ex-Bireme experts who know the CISIS-coding well but
their price was exorbitantly high, so the idea was dropped.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">However I solved most of my issues with a detour via the 'join=' parameter of mx, for this case operating on the same database itself (meaning : joining the database with itself...). That parameter indeed will
add all occurrences pointed to by the postings of the search-key into the resulting joined record. With some extra processing (with PFT or proc) the fields added with tags 3200x can be used as normal fields.<br>

In Winisis we use to have commands "l" and "lr". Apparently command "lr" was not implemented in CISIS. As we know, "l" returns the first MFN of a given key, and "lr" used to return all MFNs indexed under such key.<br>
