	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.
