	This submission contains the latest version of APLTPU, a highly
	enhanced version of DEC's EDT Emulator.  This version of APLTPU
	works under VMS V4.4-4.7 and VMS 5.0.     Included are files to
	build APLTPU for whichever version of VMS you are using.

	The following enhancements have been made since the submission
	to the Spring '88 (Cincinnati) SIG tape:

		- VMS version 5.0 support

		- Initialization files to allow users to tailor APLTPU
		  options, including their own word definitions, using
		  APLTPU commands rather than programming in VAXTPU.

		- A DCL buffer to execute DCL commands

		- Wildcards for "reference" files in split screen edit

		- Margin support

		- Bug fixes and other minor new features

	Also included in this submission are two utilities, GBLSUBS and
	GBLSEARCH.   GBLSUBS allows text substitution in multiple files 
	with full support for wildcards in file names,  and file and
	substitute confirmation.   GBLSEARCH is used to search files 
	for a given text string and to edit any files in which the string 
	is found.

	More information follows about these utilities.   If you have any
	suggestions, find a bug, or have a question, send it along. I can
	be reached either at the address above, or if you're on DECUServe,
	send mail to EISNER::BRYANT.

		    APLTPU - Enhanced EDT Emulator for TPU

	APLTPU is an enhanced version of the  EDT Emulator  for TPU which
	was distributed with VMS V4.x.    The DEC version of the emulator
	has been enhanced to include features from EVE,  EVEPLUS,  DECUS,
	and many in house enhancements.

	To use APLTPU you should define	the following symbols:

		$ TPU :== @SYS$LIBRARY:APLTPU
		$ TPUR :== @SYS$LIBRARY:APLTPUR

	and then type

		$ TPU filename

		     or

		$ TPU

	to edit	a file.	   If you don't	specify	a filename, the	last
	file that you edited will be used.  TPUR will edit a file in
	read only mode.	 TPU will also allow wildcards in filenames.

	In addition to the keys	defined	by the EDT Emulator from DEC,
	the following keys are defined by APLTPU:

		   HELP	       - Give help on APLTPU keys
				 and EDT emulator keys

		   GOLD I      - Issue initialization commands
		   GOLD $      - Issue DCL commands

		   CTRL/B      - Toggle	one/two	windows
		   GOLD	CTRL/B - Open a	reference file in second window
		   GOLD	UP     - Move to top window
		   GOLD	DOWN   - Move to bottom	window
		   GOLD	W      - Adjust	window sizes

		   GOLD	C      - Center	a line of text
		   GOLD	U      - Set case upper/lower
		   GOLD	J      - Selected substitution
		   GOLD	S      - Convert tabs/spaces
		   GOLD	E      - Trim spaces/tabs at line end
		   GOLD	T      - Convert non-printable chars
		   CTRL/V      - Enter control characters

		   GOLD O      - Toggle overstrike/insert mode
		   GOLD	B      - Toggle	box SELECT/CUT/PASTE
		   GOLD	X      - Toggle	word definition
		   GOLD Y      - Toggle graphics display

		   CTRL/K      - Start learn sequence
		   CTRL/R      - End learn sequence

		   GOLD	M      - Save current position
		   GOLD	G      - Go to saved position
		   GOLD	L      - Go to specified line
		   GOLD	Q      - Display current line/column
		   GOLD	R      - Display a "ruler"

		   GOLD F      - Toggle margin support ON/OFF
		   GOLD <      - Set left margin
		   GOLD >      - Set right margin
		   GOLD TAB    - Set TAB size

		   GOLD	V      - Display TPU version number
		   GOLD	Z      - Display the message buffer

	With this version of APLTPU,    the user can tailor many of 
	the defaults for  APLTPU  by placing  APLTPU commands in an 
	APLTPU$INIT initialization file.

	Documentation on APLTPU keys is provided through online HELP
	in APLTPU.  A cheat sheet is provided as APLTPU.HLP.

	The source files included are:

		APLTPU.TPU	- TPU source for APLTPU
		APLTPU.TXT	- Source for the APLTPU help library
		APLTPU.HLP	- A cheat sheet
		EDTSECINI.TPU	- The source to DEC's EDT Emulator,
				  included here with permission of
				  Digital, since it is not distributed
				  with VMS 5.0.
		APLTPU.COM	- Procedures to invoke APLTPU with
		APLTPUR.COM	  filename recall and wildcards.

	BUILD.COM can be used to build and install APLTPU.   Note that
	APLTPU has some minor conditional assemblies for VMS V5.0.  If
	you want to give it a quick try,   section  files are included
	in this submission: APLEDTSECINI (VMS V4.X) and APLTPU$SECTION
	(VMS V5.x).

	    GBLSUBS - Utility to substitute text in multiple files

	This utility allows you	to replace all occurances of a string
	with another string in a list of files.	   GBLSUBS is invoked
	as follows:

		$ @TOOLS:GBLSUBS file(s) search_string replace_string

	You will be prompted for any unspecified parameters.  Options
	are specified as switches for a	file:

		/Confirm - will	ask you	to confirm each	file
		/Exact	 - will	do a case sensitive search
		/Query	 - will	ask you	to confirm each	substitution

*******************************************************************************

                GBLSEARCH - Utility search and edit/read files

	This utility allows you to SEARCH files for a string and to edit
	files containing the string.    GBLSEARCH is invoked as follows:

		$ @TOOLS:GBLSEARCH file(s) search_string edit/read


	You will be prompted for any unspecified parameters.    Options
	are specified as switches for a file:

		/Confirm - will ask you to confirm each file
		/Exact   - will do a case sensitive search
		/Names   - will display the names of all files searched

	The default is to edit files read only.
