.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.
