       The parameter name, as a string.

      <note>
       <para>
        You have to include the <literal>@</literal> character, like in the
        T-SQL syntax. See the explanation included in
        <function>mssql_execute</function>.

     <listitem>
      <para>
       The PHP variable you'll bind the MSSQL parameter to. You can pass it
       by value, or by reference, to retrieve OUTPUT and RETVAL values after
       the procedure execution.

       One of: <constant>SQLTEXT</constant>,

       <constant>SQLINT1</constant>, <constant>SQLINT2</constant>,

    <varlistentry>
     <term><parameter>is_output</parameter></term>
     <listitem>
      <para>
       Whether the value is an OUTPUT parameter or not. If it's an OUTPUT
       parameter and you don't mention it, it will be treated as a normal
       input parameter and no error will be thrown.

    <varlistentry>
     <term><parameter>is_null</parameter></term>
     <listitem>
      <para>
       Whether the parameter is &null; or not. Passing the &null; value as
       <parameter>var</parameter> will not do the job.

     <listitem>
      <para>
       Used with char/varchar values. You have to indicate the length of the
       data so if the parameter is a varchar(50), the type must be 
       <constant>SQLVARCHAR</constant> and this value <literal>50</literal>.
