Dean elsner. These are submitted for application to the DECUS C package.

[272,31]	ALGOL68.H

ALGOL68.H	I use this #include file to write C that my fellow
		programmers (at least until they are re-captured)
		can use and read. This was evolved when I had to
		pay professional rates to these people. Because of
		our style, the number of bugs we did not write 
		was very high.

		Examples of using this are all over these submissions.
