For those who are interested in my ongoing Forth-in-Python works, you can get it by joining http://www.egroups.com/files/SynthetoForth/ and looking into the files section. This was the easiest way to place it somewhere on the net, without having to mess with CVS at SourceForge or so, or creating my own website. (I'm really not interested in investing time into Web content creation or so, just had to place those files somewhere for communication.) Of course, if you don't wanna give egroups your personal data, you might as well mail me directly... at the moment, i'm rewriting it every day a little. It's quite tricky to get it right so the real Forth magic gets preserved; Chuck Moore is said to have it rewritten a multitude of times before it became the classical 70ies Forth. Be warned, maybe my newer versions get too tricky to be of interest for a little educational intro into postfix. I'm seeing now that the infix vs. postfix syntax item is only very surfacial, the magic is much deeper (the key to the extensibility of Forth). (still i don't know whether it can be delivered to other languages. I don't know whether is has ever been tried, or whether there are such languages. Maybe it can only work with a language as simple as Forth, and every attempt to give the language more syntactical sugar destroys it. The truth hides.) Dirk
