This help system requires a browser that supports frames. This is
because it would be extremely difficult to navigate round the help file without frames.
When I have time I will write further pages for those whose browsers do not support these
functions. In the meantime, please accept my apologies. There are many browsers available
that support these functions including MicroSoft's Internet
Explorer and Netscape Navigator (which are both
free). Why not treat yourself to an upgrade?
The 
allows you to return to the previous link irrespective of
which page that was on. However, it will be disabled if Javascript is not
supported by your browser.
If your browser does support
frames and JavaScript then click here (or on the graphic below)
for the help pages.
