.SH Description
.NXR "nl macro"
.NXR "nonl subroutine"
The 
.PN nl
routine enables the newline control translations.
When newline control is enabled,
a newline is translated into 
a carriage return
and a linefeed on output, and a return is translated into 
a newline on
input.
Initially, these translations do occur.
.PP
The
.PN nonl
routine
disables these translations, 
allowing
the
.PN curses
program to use the
linefeed capability
of the terminal,
resulting in faster cursor motion.
The
.PN nl
routine
is a macro.
.SH Return Values
The
.PN nl
and
.PN nonl
functions return OK on success and ERR on error.
