Unfortunately I am in need of an entire Greek alphabet because 
automatons that have already been created with this program should 
continue to work and be displayed correctly.

Great!
If you could guarantee me your assistance at least for the Trestle/VBT 
issues in support of 16bit wide characters I would start to work on a 
Modula-3 port. The thing is that I will need the port for my studies and 
I do hardly want to take the risk in failing to hack Trestle/VBT though 
the thing should not be that hard to do as Olaf has already indicated. 
As far as I have researched things all that would need to be done is add 
an additional painting operation to the PaintPrivate interface; or 
perhaps a second one for drawing elliptical arcs rather than just using 
Path.CurveTo and to make these new operations be used by the respective 
painting primitives. Additionally I would welcome some styling of 
buttons and bevels that goes ahead of pure black and white X-windows. 
Some Qt-like or at least a Windows 3.1 like button and menu styling 
might not  be unimportant for the acceptance of the application. 
Nonetheless up to now I can not verify the impact of new painting 
operations on ports for Windows and MacOS which I am not confident with.

No, it does not have a single goto; I`d consider it well structured as 
it uses classes, objects, method variables and nested procedures and can 
easily be extended for new automatons. At the moment I am still reading 
into Trestle.

P.S.: I have already programmed a module converting between UTF-16 and 
UTF-8 for console usage and am ready to publish it under BSD or any 
non-infective license allowing to re-license under any license. I would 
consider it really a pity if CM3 had good internal UTF-16 support but no 
interface to make use of it in practice.

Additionally I could upload my still existent VIM environment for 
hacking Modula-3 including syntax highlighting, a treeview buffer and a 
backtrace analyzer to http://www.elstel.org/modula3 if anyone is 
interested in it.
