+This paper is an introduction to programming on
+the
+.UX

+The emphasis is on how to write programs that interface
+to the operating system,
+either directly or through the standard I/O library.
+The topics discussed include
+.IP "  \(bu"
+handling command arguments
+.IP "  \(bu"
+rudimentary I/O; the standard input and output
+.IP "  \(bu"
+the standard I/O library; file system access
+.IP "  \(bu"
