     The PDO_IBM Data Source Name (DSN) is based on the IBM CLI DSN. The major 
     components of the PDO_IBM DSN are:

      <varlistentry>
       <term>DSN prefix</term>
       <listitem>
        <para>
        The DSN prefix is <userinput>ibm:</userinput>.

      <varlistentry>
       <term>DSN</term>
       <listitem>
