thanking many people's interest on the previous product of our project,
MOOD/P3, now we have made anonymous-ftp'able from

     mood.mech.tohoku.ac.jp (130.34.88.61)

a more portable and readable version, MOOD/P3-PC. 

     MOOD/P3(-PC) is a general purpose OODBS program. yet we call this
for "Material's data" and post this in this news-group because we
think that this much capability is needed to deal with material data
whose contents tend to spill out of the ability of conventional
database systems. from its release note:

 ====================================================================
 MOOD/P3-PC ver.1.00:
 Material's/Miniature Object-Oriented Database Prototype for
 NEC/IBM-PC,

is an object-oriented database system program and does exactly the
same thing as our previous release, MOOD/P3, which was exclusively for
NEC/PC-9801. See, therefore, the manual for MOOD/P3 in ../doc if you
are interested in what it is all about.

     this release is made in the form of source program files to be
consulted and run on Arity/Prolog interpreter. the program is supposed
to be portable among NEC/PC-9801, its clones, IBM-PC and its clones
with MS-DOS and Arity/Prolog Interpreter. We could have tested this
on:
	1) NEC/PCs with MS-DOS 3.3
	2) a nameless IBM-PC clone machine with MS-DOS/V, both in Japanese
and English modes.

we are not very sure if this program runs OK in other IBM-PC
environment. we would be very pleased indeed if you tell us the result
you get on your machine.

     making MOOD/P3 portable was accomplished by removing the usage of
C-functions which rely on particular hardware configulations of
NEC/PC. This results in the abolision of

     1) the use of graphic drawings in display things,
     2) the use of mouse,
     3) hardware dependent scrolling and screen saving/restoring.

the first wouldn't matter much and the second would have made things a
bit inconvenient. The third should have made the program slower;
however, we think we have overcome this by changing the methods of
pretty-printing and focus manipulations.

     rather, these changes make the program simpler and more readable
so that this release would provide better platform to which you may
put in further inovations in regard to OODBS functionalities and user
interface behavior. we are pleased to hear these from you.

     In association with the above change, key assignments are
slightly changed from those described in the MOOD/P3 manual. the new
key assignments can be found in the source program file, EO.ARI, or in
menu display invoked by hitting H in Object-Editor.

     also, the function of class-tree display is largely enriched;
we now call it the class-manager which is capable of:

     1) cruising entire class tree,
     2) edit a class,
     3) moving a brach by rewriting the superclass in the above,
     4) deleting an unnecessary class.

the key-command menu for the class-manager, promptings and source
program, CLASSMGR.ARI will explain its use.

==================================================================

     We hope you will enjoy this program. mails telling bugs,
inconveniences, objections will be appreciated.
