				    OPALjr
				 Version 1.01
				 1 April 1991


OPALjr is not copy protected, so you may make working copies for all of your
personal computer systems.  For additional copies of the software and manual,
or to request information regarding the full OPAL package, contact your local
National Semiconductor representative.  For technical assistance or to report
software bugs, you should contact the appropriate office listed below:

		Region			Telephone Number
		------			----------------
		U.S. and Canada		(408) 721-2092

Installation of the OPAL software is accomplished by running the "install"
program located on this disk.  This program will copy all of the necessary
files into the specified directory on your hard disk.  It will also create a
batch file called "new_auto.bat" to use as an example for configuring your
system so that it can later find the OPAL executable files.  OPAL fully
supports paths so that project separation can be maintained on your disk.

This disk should contain:
	README
	OPAL    .EXE
	OPAL    .HLP
	EQN2JED .EXE
	JED2EQN .EXE
	PAL2GAL .EXE
	OPLCHECK.EXE
	OPALVIEW.EXE
	OPALVIEW.HLP
	DEVICE  .LIB
	DEMO\*.*
	EXAMPLES\*.*

To work with OPALjr on a floppy disk system with only a single low-density
floppy disk drive, you will have to forgo the use of the OPAL graphic shell.
Copy the following files and directories onto the floppy disk:
	EQN2JED.EXE
	JED2EQN.EXE
	PAL2GAL.EXE
	DEVICE .LIB
	\EXAMPLES\*.*

To work with OPALjr on a floppy disk system with a high-density floppy disk
system, simply make an exact copy of the OPALjr release diskette.


Additions to the manual:
------------------------

The OPAL graphical shell provides a demonstration of the complete OPAL package
under the "Help" menu.  This demo explores the features of both the OPALjr and
full OPAL packages.

The OPAL graphical shell provides full user help capabilities at any time by
using the F1 key.  For example, if you are currently within the editor, just
press F1, and you will get a complete description of all editor commands and
keystrokes.

The program OPLCHECK.EXE is being provided as an introduction to the OPL
programming language.  This program will perform a syntactic check of a
supplied design file and tell you if there are any errors.  It is intended to
be used to determine if the full OPAL package will support any features you
are interested in.  For more information, please contact the appropriate
number listed above.
