NAME

       form_page - set and get form page number


SYNOPSIS

       #include <form.h>
       int set_current_field(FORM *form, FIELD *field);
       FIELD *current_field(const FORM *);
       int set_form_page(FORM *form, int n);
       int form_page(const FORM *form);
       int field_index(const FIELD *field);


DESCRIPTION

       The  function  set_current field sets the current field of
       the given form; current_field returns the current field of
       the given form.

       The  function  set_form_page  sets  the form's page number
       (goes to page n of the form).

       The function form_page returns  the  form's  current  page
       number.

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