Opus 2.2 ReadMe
Release Date: 8/12/89
---------------------


To: New users
-------------

Please read the file INSTALL.DOC before attempting to run Opus; it
contains important information about setting things up for GDOS. The
OPUS22.DOC file is really a manual addendum. If you are having difficulty
learning Opus and find the online help inadequate, or you would like to
see some sample worksheets, download the file OPUSDOC.ARC. It contains
several worksheet files as well as the documentation for version 2.1,
which is mostly applicable to version 2.2 (OPUS22.DOC supersedes
OPUS21.DOC in certain areas).

Since the Swiss 10 point font is included with every GDOS package I'm
aware of, Opus 2.2 uses this as its default for all chart text items.
You may change this on an item by item basis to whatever font you
have available.

To: All users
-------------

To use the new help feature of Opus 2.2, create a folder OPUSHELP in
the directory containing OPUS.PRG. Then transfer all the help files to
that folder. The help files are found in HELP.ARC within the OPUS22.ARC
file.

To: Current users
-----------------

Your current PRINTER.INF, OPUS.CNF, and OPUS.WID files are compatible
with Opus 2.2. However, Opus 2.2 does save additional information in
the OPUS.CNF file. Two new default paths are saved: WKS/WK1 and DIF.
DIF isn't used yet, but it will be later on. In addition, the default
settings of the new chart features are saved.

Please be sure to at least read the "Copy/Move" and "Insert/Delete
Row and Column" sections in OPUS22.DOC, for these worksheet functions
have undergone some significant changes.

Re: Scrollable lists
--------------------

To deselect items, earlier versions required you to click anywhere
outside the list but within the dialog. I often found myself
unintentionally deselecting items, so this method has been changed.
Now, click within the "margins" of the list to deselect an item. For
example, if the list looks like:

   ------------------
   |****************|
   |**d-mmm-yy    **|
   |**mmmm d, yyyy**|
   |****************|
   ------------------

click within the area indicated by the asterisks (this area is of
course blank in the actual dialogs). This affects the number and
date/time format dialogs.

Sorry for the inconsistency; this will be the finalized method.

Re: Charting
------------

Opus 2.2 allows you to position chart titles and legend with the
mouse. However, if you want your worksheet files to be portable
from the monochrome monitor to the color and vice versa, Character
Spacing should be in effect when you place the titles. Otherwise,
you'll likely find the titles slightly out of place when used on
the "opposite" monitor.

Opus 2.2 uses line patterns to distinguish between chart data series
when appropriate. Splines and other smooth curves are constructed from
a set of line segments, and you may find that the patterns "get out of
sync" on some curves; that is, a dotted pattern may show more dots
than it should. This seems to be more of a problem with the screen
than with the printer and apparently is an ST limitation.

A number of users have pointed out that EasyDraw has problems with
Opus metafiles. Text isn't justified properly, filled area outlines
are lost, vertical axis titles aren't displayed rotated, scaling of
the chart as a whole isn't very accurate, etc. Well, what can I say.
One of the main reasons I bought EasyDraw was to use and test with
Opus metafiles, so I'm disappointed too. My conclusion is that although
EasyDraw uses the GEM metafile as its file format, it is not a generic
metafile player, much less a generic metafile editor. This is supported
by the fact that Publisher ST and OutPrint/Output do splendid jobs with
all Opus metafiles. While I could make an effort to make my metafiles
"EasyDraw-compatible," about the only improvement would be drawing of
outlines around filled areas. EasyDraw simply doesn't support rotated
text or justification of text in a manner other than its own. Furthermore,
I can't do anything to improve EasyDraw's accuracy in scaling metafiles.
Since the things I _can't_ fix are fundamental to producing presentation
quality graphics, I can't justify the time and effort to fix the few
things I can.

Finally, I've occassionally noticed very minute breaks in regression
lines when printed at 300 DPI on a Hewlett Packard DeskJet. This is
an infrequent problem, and it occurs with lines printed at certain
angles. I mentioned this in a letter to Migraph, and they attribute
it to limitations in the Digital Research (author of GEM) printer driver
code, upon which most, if not all, ST GDOS printer drivers are based.
They say they seldom hear complaints about this, and I'll agree it's not
too serious a problem. In any event, Migraph is aware of it and is
working on a fix.
