42 Here we present a few examples
43 of how to use the package.
44 They attempt to be representative,
45 though not comprehensive.
46 Further examples can be found in the games section
47 of the source tree and in various utilities that use the screen such as
50 The following examples are intended to demonstrate
51 the basic structure of a program
53 An additional, more comprehensive, program can be found in
54 the source code in the
55 \fIexamples\fP subdirectory.
56 .sh 2 "Simple Character Output"
58 This program demonstrates how to set up a window and output characters to it.
59 Also, it demonstrates how one might control the output to the window.
60 If you run this program, you will get a demonstration of the character output
61 chracteristics discussed in the above Character Output section.
67 This is a moderately simple program which prints
68 patterns on the screen.
69 It switches between patterns of asterisks,
70 putting them on one by one in random order,
71 and then taking them off in the same fashion.
72 It is more efficient to write this
73 using only the motion optimization,
74 as is demonstrated below.
