SYNOPSIS
       #include <form.h>
       int set_current_field(FORM *form, FIELD *field);
       FIELD *current_field(const FORM *);

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.
