Algol 68 (free system available from... see url below) (a horizontal dial program)

The only system that I have been able to find after months of search (meaning you will tell me of a million others!) is at:-

http://www.xs4all.nl/~jmvdveer/algol.html

While this is a free open source systrem, and is a command line system, it runs on Windows XP and Windows Vista win64. To make the system easier to use, I provide a batch file
which brings up the horizontal dial source program, you exit that, then the Algol system runs the program.

NOTE: The Algol system is open license and the downloadable executable from the Algol Genie author's is in a “tgz” form but downloads as a “.tar” file, so you must change the “.tar”
suffix back to “.tgz” because Winzip will otherwise get very upset. The system is open source, so my zip file has everything you will need. The Illustrating Shadows web site zip file is
normal zip format.

With the exception of download changing the executable suffix (see above), it worked first time, has a manual, and works. I have, as always, placed into my notes the command line to
compile, and my notes also have a batch file to do it all, and it begins with editing the program, then compiling, then linking, then running, then viewing the output.

This is part of my battle to bring back the legacy languages so diallists can have fun with their journey into gnomonics. I learned Algol for the Elliott 803 computer at college, after which I
learned the IBM 1401 system (Autocoder and SPS) then the IBM 360 system.

Download t his file which has my notes, the source program, the Algol system and documentation, all open license.

Same process for win64 Vista
