	The following subdirectories are present; the contents include
materials as documented below. Browse other AAAREADME.* files too, please,
for further information. The network material is unindexed but has VERY
long filenames to make it easier to find things.

[.ANALYBIG]		AnalytiCalc spreadsheet (src, obj, exe). AnalytiCalc
				used to have lots of 16-bit integer variables
				inside to allow efficient work on PDP11 or
				IBMPC. This version has mostly 32 bit 
				variables (good for Amiga and VAX) and will
				let you define as egregiously large spread-
				sheets as you want. It runs faster than the
				version with i*2 variables too! Also a couple
				new cell address modes are added to make it
				easier to write address calculations in your
				macros for it, and the binary save/load mode
				is speeded up over the old text mode (which
				is still available for compatibility and
				transportability.)
[.TARRDWRT]		Local TAR read/write mods. Allows ANY sequential
				file to be written to TAR tape and allows
				partial squashing of too-deep Unix directory
				trees.
[.VMSVD]		Virtual disks for VMS!!!
				The old VDDRIVER is fixed so it handles
				all split I/O correctly and is cleaner.
				This driver makes a contiguous file on a
				VAX system local disk appear to be a totally
				independent volume, with high performance.

				Also, a new driver FDDRV is introduced.
				It provides:
			   * Remote virtual disks over DECnet or asynch,
				so you can back up a disk over a network
				from a machine without a tape, EXACTLY
				as if the remote disk were a local device.
				(Note: Be sure your RMS network buffers are
				set to 17 or more, or edit the source to the
				remote disk host/server routines, before
				using the DECnet remote disks. They expect
				to be able to send 8300 byte DECnet $QIO's.)
			   * Memory disks, using a PROCESS' address space.
				Thus the VMS paging algorithm determines what
				memory is actually in physical memory. No more
				eating your nonpaged pool alive!
			   * File disks. Data stored on a file, which does NOT
				have to be contiguous. (This can be used even
				on the most fragmented disks!) Files can be
				on other DECnet nodes also, if this is desired.
			   * Crypto disks. Data is stored in a file, as in the
				file disk, but is encrypted on write and
				decrypted on read. This gives a trivial way to
				have storage automatically used by existing
				software in encrypted form, and is the
				simplest way to solve problems like wanting
				to have one's payroll file online, but secure
				against perusal by the systems people after
				hours (or even, with a few caveats, during the
				time the disk is in use). In spite of the fairly
				high strength of the encryption, the routines
				run rather quickly and impose no noticeable
				burden even on a 750.
			   * Bat Out of Hell Disk. This is a combination
				memory/file disk, whimsically named. The idea
				is that it is functionally a file disk
				shadowed by a (process based) memory disk,
				so that all reads are from the memory disk
				while writes go to memory AND the file disk,
				providing safety in case of crashes. As
				in the "standard" file disk, the file does
				not HAVE to be on a local node.

		Since a normal VMS process does all the physical I/O for
		FDDRV, you can create your own flavors of remote disks
		with it...WITHOUT even having to write any kernel mode
		code! That's been done for you.

[.NETS89]		Giant cornucopia of messages with source code, hints
				and tips on keeping your system healthy
				and happy, gleaned from Internet sources.
				Includes a very interactive disassembler.
				Also Sid Penstone's latest TAR read/write
				utilities.
				Sources only in most cases.

[.ADASIMSCRIPT]		SIMSCRIPT - similar package written in Ada
[.BROWSER]		Browser/Indexer. Allows full text retrieval of
				data by one or MORE keywords, in definable
				neighborhoods, from ANY text file. Fast, 
				too! Somewhat crufty but not too obscure
				user interface. Worth using!
[.NETS89.MISCUTL]	Browser src; VMS MSDOS diskette reader; B-Tree
				source code; PD sources for ARC.
[.NETMAP]		Old DECnet mapper utility. Worked for DECnet phase
				III (one area). Source.
[.TARDR]		TAR reader/writer code for VMS, locally modified.
