Subject:  DECtree U2.3 Field Test Release


Tool Description
----------------
DECtree is a tool that allows you to create, modify, build, and execute 
decision-tree based applications via a graphical user interface.  With 
DECtree you can capture, maintain, and distribute key expertise throughout 
your enterprise. 

DECtree makes all of this easy for nonprogrammers by translating decision 
trees into C programs and by building these C programs into applications 
(.EXE files).  DECtree is also powerful enough for advanced programmers to 
build complex, real-world applications.  

Both the DECtree development environment and the DECtree run-time environment 
run on all three of Digital's workstation platforms (VAX/VMS, VAX/Ultrix, and 
MIPS/Ultrix).  The DECtree run-time environment also runs on character cell 
terminals.

Please post your questions and problem reports in the AIAG::DECtree VAXnotes
conference.  If you have any non-technical questions or issues, please feel 
free to contact the Product Manager at dtn 291-8104 or AIAG::Lutz.

Installation Kits
-----------------
The VAX/VMS VMSinstal kit is located at:

	AIAG::DECTREE$:[KIT]DECTREE023.A


For further information, you can look at the file:

	AIAG::DECTREE$:[KIT]KIT_CONT.TXT

This shows the DECtree files that are included in the kits and their sizes.  
Actual installation requires twice the amount of disk space for the kit.



VAX/VMS Installation
---------------------
VAX/VMS installation should be executed from the SYSTEM account (by the 
System Manager).

	$ SPOOL COPY AIAG::DECTREE$:[KIT]DECTREE023.A []
	$! Wait for the SPOOL to send a message that it has completed
	$ @SYS$UPDATE:VMSINSTAL DECTREE

DECtree VAX/VMS Kit Size:		13,800 blocks
Disk usage during installation:		28,000 blocks
Permanent disk usage:			13,800 blocks



Running DECtree 
---------------

To run DECtree from VMS:

    $ dectree



After you have installed DECtree
--------------------------------
Please send a message to AIAG::DECTREE informing us that you are using DECtree.
We're interested in knowing --

	o  Hardware that you are using

	o  What you are using DECtree for

	o  How many people are using your DECtree applications

This information will help us plan better for DECtree's future.



If you have any questions, comments, issues, and especially bugs, please let us 
know.  I can be reached at AIAG::Lutz, and the DECtree notesfile is available 
at AIAG::DECtree.  Your comments and feedback are greatly appreciated by the 
DECtree team.  Thanks for working with us!
