I have now added two more documents to the collection of documents about
1456 object code and its applications on
http://www.users.globalnet.co.uk/~ngo which is our family webspace here in
England. 1456 object code allows users who may not have Java knowledge or
Java facilities to obtain Java quality graphic output by programming in 1456
object code in 7 bit ascii printing characters using a text editor in an
HTML file.
These two latest documents are about a 1456 applet landscape called
Dual1456. The working program may be accessed directly from the web using
http://www.users.globalnet.co.uk/~ngo/Dual1456.htm and there are also notes
about the system available from the index. It is an applet on a web page
and thus safe to run with confidence.
This program at start up looks the same as does the previously published
demo7.htm customization of the Softboard1456.htm program. However, there is
the additional facility that one can switch between two softboard toolbars.
One starts with a softboard toolbar that has the characters for English and
Esperanto and one can switch, by clicking near the top left corner of the
background area of the applet, to a softboard toolbar that has Greek
characters. One can return to the original English and Esperanto softboard
toolbar by clicking again near the top left corner of the background area of
the applet The resulting display can include characters obtained from both
softboard toolbars. At start up the screen display looks exactly like the
display from the demo7.htm file. A different 1456 applet landscape is used
to support this process and it uses two 1456 engines, one for each of the
two softboard toolbars, though this use of two 1456 engines, or even the use
of 1456 object code at all, is not apparent to someone who is simply using
the program.
I have used English, Esperanto and Greek characters. The system is designed
to be customizable using a text editor and using any printing unicode
characters that can be expressed with four hexadecimal characters and for
which the locally available fonts make provision.
