If you really want to write just a "translator" from Tcl to Scheme, keeping semantics of original program, there's nothing different from ordinaly compiler problem. However, I got feeling that what you're looking for is a way to interoperate Tcl code and Scheme, right? In that case, I guess you can define some semantics by yourself: ("if it looks like a number, translate it to Scheme number" like that). STk (http://kaolin.unice.fr/STk/) has a nice integration of Tk's everything-in-string policy and Scheme. You may want to look at it. Or I might miss your point. Could you explain your project further? > (I don't know how they byte-compile > TCL -- the language seems practically designed to make it hard to > compile by convential means). Why? Of course Tcl's nasty "dynamic" nature (like consisting variable names at run-time) makes it difficult to resolve all symbol references at compile time, but you can still embed an instruction to do symbol lookup at runtime. -- Shiro KAWAI Square USA Inc.
