			       EROS DATA CENTER


	The following programs have been submitted by the USGS/EROS Data center;


	[EROS.DLA]

		This directory contains DLA, a program that provides the
		often requested feature "date of last access" for VMS files.

	[EROS.MASTER_BLASTER]

		This directory contains MASTER_BLASTER, a program which
		trims working sets in order to conserve memory.  We went
		from an average of 3000 free pages of memory to an average
		of about 14000 free pages on a 16mbyte system, with no apparent
		adverse effects.

	[EROS.POKE_WATCH]

		This directory contains POKE_WATCH, a program which turns on
		the undocumented VMS "watch" feature which has been mentioned
		in Pageswapper.  This was written to provide an audit trail of
		files accessed by remote users of our default proxy DECNET.

	[EROS.SPLIT]

		This directory contains SPLIT, a utility which calculates the
		percentage of elapsed uptime wasted due to split disk I/O's
		and window turns, which are caused by disk fragmentation.  Use
		this to show management that you really do need that defragger!

	[EROS.TPT]

		This directory contains TPT, a tape drive benchmark program.  It
		provides statistics such as bytes/sec and inches per second.
