/*
 * Function:
 *
 *	Similar to 'od -cx' but with more concise format
 *
 *	Dump a file in hex and printable on the same line.
 *	Quick, dirty, works.  Non printing chars are displayed
 *	using the NONPRINT char, and the 16 byte printable is
 *	delimited by the WALLS char.
 *
 *	Copyright 1989 by E. Clarke.  Released to Public Domain
 *	with no restrictions.  Sell it if you can find anyone
 *	dumb enough to buy it.
