C/C++ Books Ö I found öC For Dummiesò from IDG Books a perfect tutorial.
Itæs informal and American, but it explains everything in a very
comprehensible manner. The ISBN is 1-878058-78-9 and it costs ú18.99,
although IDG Media in the UK (the publisher of Acorn User) may be able
to do you a special deal. The company also produces a öFor Dummiesò book
on C++.

A circle in perspective Ö Most drawing programs can draw an ellipse.
Most artists will use this when drawing (say) the top or bottom of a
vase, but a circle in perspective is not an ellipse!!
9.11
Firstly, choose a square to fit the circle. Draw this square, with its
diagonals, in perspective to a suitable vanishing point, as shown. Where
the diagonals cross, draw the line marked Édiameteræ. Draw the line OA.
This is used to draw an octagon in perspective.
9.11
Construct the octagon ... Where the line AO cuts the diagonals, draw
horizontal lines to D and C. Do similarly for E and F on the other side.
9.11
Draw a continuous curve to touch the centres of the sides of the octagon
(where the sides cut the diagonals and diameter).
9.11
Click on the bottom icon of the toolbox to get the dotted box around the
drawing. Use the Éhandlesæ to alter the size and shape! Copy it, then,
anywhere you like!

Internet data overload Ö I found that I was keeping more and more items
from the internet newsgroups, just in case I needed to refer to them
again, such as FAQ, useful contacts, or WWW addresses. But, of course,
trying to find anything with only file names to go on was impossible.
9.11
I thought about designing a database in my database package, but then a
Clares advert suggested Knowledge Organiser II. I found someone who had
a demo, but that only showed searching, not creating a database, but I
took a chance anyway and decided to buy it with the aim of getting
organised. I havenæt regretted it Ö the demo does not do it justice!
9.11
KO II is all about storing text and giving it references to make it easy
to find again. Perfect for this use. As well as the built in context
code fields, you can add your own Ö which I didnæt realise at first. So
my database has a field for the news item title, plus date downloaded,
and then uses the KO II context code fields to Édescribeæ the entry. You
can also add more codes as you gradually learn your search requirements.
Iæve already been able to search for things I stored days before, going
straight to the article instead of guessing, wrongly, where I put it.
9.11
The package could do with a couple of improvements which I have
suggested to Clares, but I would certainly recommend it for anyone
struggling as Iáwas. KO II costs ú75 through Archive.
