## 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.
