    form_data(3x)                                                    form_data(3x)

## NAME

           data_ahead, data_behind - 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).

## SEE ALSO

## 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.
