       <STRONG>#include</STRONG> <STRONG>&lt;form.h&gt;</STRONG>
       int set_current_field(FORM *form, FIELD *field);
       FIELD *current_field(const FORM *);
       int set_form_page(FORM *form, int n);

</PRE>
<H2>DESCRIPTION</H2><PRE>
       The  function  <STRONG>set_current</STRONG> <STRONG>field</STRONG> sets the current field of
       the given form; <STRONG>current_field</STRONG> returns the current field of
       the given form.

       The  function  <STRONG>set_form_page</STRONG>  sets  the form's page number
       (goes to page <EM>n</EM> of the form).

       The function <STRONG>form_page</STRONG> returns  the  form's  current  page
       number.

       The function <STRONG>field_index</STRONG> returns the index of the field in
       the field array of the form it is connected to. It returns
       <STRONG>ERR</STRONG>  if  the  argument is the null pointer or the field is
       not connected.
