.sh 1 "Examples" 1
.pp
Here we present a few examples
of how to use the package.
They attempt to be representative,
though not comprehensive. Further examples can be found in the games section
of the source tree and in various utilities that use the screen such as
.i systat(1) .
.pp
The following examples are intended to demonstrate
the basic structure of a program
using the package. An additional, more comprehensive, program can be found in
the source code in the
\fIexamples\fP subdirectory.
.sh 2 "Simple Character Output"
.pp
This program demonstrates how to set up a window and output characters to it.
Also, it demonstrates how one might control the output to the window. If
you run this program, you will get a demonstration of the character output
chracteristics discussed in the above Character Output section.

.sh 2 "Twinkle"
.pp
This is a moderately simple program which prints
patterns on the screen.
It switches between patterns of asterisks,
putting them on one by one in random order,
and then taking them off in the same fashion.
It is more efficient to write this
using only the motion optimization,
as is demonstrated below.
