SYNOPSIS
#include <form.h>
int set_current_field(FORM *form, FIELD *field);
FIELD *current_field(const FORM *form);
int unfocus_current_field(FORM *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 unfocus_current_field removes the focus from the current
field of the form. In such state, inquiries via current_field shall re-
turn a NULL pointer.
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 ar-
ray of the form it is connected to. It returns ERR if the argument is
the null pointer or the field is not connected.
