	A short program in C. It was inserted directly into the \TeX\ source file.

	\medskip
	\BeginC
	#include <stdio.h>

	void main()
	{
	a=~a;
	printf("Hello, world!\n");
	// printf("Hello, world!\n");
	}
	\EndC

	\hrule
	\bigskip

	And now a program inserted from a separate file.

	\medskip
	\InputC{prog/sun.c}

	\vfill\eject


	And now programs written in Pascal. This one was typed directly into this
	file.

	\medskip
	\BeginPascal
	program Hello_world;
	begin
	writeln('Hello, world!');
	{ writeln('Hello, world!'); }
	end.
	\EndPascal

	\hrule
	\bigskip

	This one was imported from another file.

	\medskip
	\InputPascal{prog/guess.pas}

	\vfill\eject

	And now, my latest addition: programs written in Python. The first one
	is typed directly into the file.

	\medskip
	\BeginPython
	def fib(n):
	"""Calculates Fibonacci series.

	It returns the first member of Fibonacci series larger than n"""
	a,b=1,1
	while b <= n:
	a,b = b,a+b # see how we use multiple assignment?
	return b

	fib(10)
	\EndPython

	\hrule
	\bigskip

	This one was imported from another file.

	\medskip
	\InputPython{prog/fib.py}

	\bye
