    <Paragraph position="0"> The experiments described below have been done in connection with the LS-GRAM project 1, which is concerned with the development of large scale grammars. The specifications of the project foreseen the coverage of &amp;quot;real life texts&amp;quot;, which have also been processed by a corpus analysis. The resuits of the corpus analysis allowed us to determine a priority list of the linguistic phenonema to be described. And in order to deal with &amp;quot;real fife texts&amp;quot;, it is also necessary to consider the processing of linguistic units, which are larger than sentences. And as it is well known, the interpretation of sentences embedded in larger units is often distinct from the one of sentences, which are standing on their own.</Paragraph>

    <Paragraph position="2"> The resolution of cross-sentential anaphora is one of the problems we have to deal with, when we switch towards the analysis (or synthesis) of such larger linguistic units. In order to give a correct interpretation of the cross-sentential anaphora, one has to be able to refer back to an antecedent, which is to be found in a preceding sentence, and I am using the term information-passing exactly in this sense: some information about a possible antecedent must be stored in order to be passed on to following sentences and to allow the anaphoric link, if some of the subsequent sentences are containing an anaphoric pronoun. Using the simple unification technique, as for the processing of other linguistic phenomena within ALEP, a resolution of the pronoun can then be tried out: parts of the content information of the pronoun are going to be compared (unified) with specific parts of the content information of the (possible) antecedent.</Paragraph>
    <Paragraph position="3"> In the next section I will first show how larger linguistic units can be processed within the ALEP system. In a second section I will very briefly present a semantic framework, which introduces the idea of &amp;quot;information-passing&amp;quot; in order to cope with cross-sentential anaphora: the Dynamic Predicate Logic (DPL). In the last section I will show how a very preliminary and tentative implementation of this framework can be modelled within the ALEP forrealism. Even if this first implementation is somehow primitive, this will permit us to formulate some remarks about the allowed degree of modularity of grammar descriptions within ALEP and also about the way in which such descriptions can be extended.</Paragraph>
    <Paragraph position="4"> These are two important aspects if one considers the task of developing large scale grammars.</Paragraph>
