## NAME

           form_data - test for off-screen data in given forms

## SYNOPSIS

           #include <form.h>
           bool data_ahead(const FORM *form);
           bool data_behind(const FORM *form);

## DESCRIPTION

           The  function data_ahead tests whether there is off-screen
           data ahead in the given form.   It  returns  TRUE  (1)  or
           FALSE (0).

           The function data_behind tests whether there is off-screen
           data behind in the given form.  It  returns  TRUE  (1)  or
           FALSE (0).

## NOTES

           The header file <form.h> automatically includes the header
           file <curses.h>.

## PORTABILITY

           These routines emulate the System V forms  library.   They
           were not supported on Version 7 or BSD versions.
