## NAME

           data_ahead,  data_behind  -  test  for  off-screen data in

## 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

           file <curses.h>.

## PORTABILITY

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