I did mine in the exact opposite order, and am pleased with the result. I parsed into data structures, and only recently have I translated into byte-codes. I view byte-codes as a largely irrelevant internal implementation detail, and there is no way for the users to enter them, other than through the programming language. There is a 'disassemble' builtin that I've used for debugging, and will leave in just for interest's sake. The disadvantage of what you suggest is that you are throwing away a good portion of the possible speed. One reason is that it is the lack of any need for run-time checks (other than things like divide-by-zero) that makes my byte-code so much faster than, say, Java byte-code. I figure the only reason to use byte-code rather than some other interpretation scheme is because you want maximum speed. So, why then cripple that speed? Inventing a byte-code and then doing something like an assembler for it, is doing a whole lot of work that there really isn't a need for. Why would anyone want to program in byte-code assembler? If the byte-code is tuned to the higher-level language, then the compiler-generated stuff will be just about as fast as any hand-coded stuff, even without a fancy compiler. Remember the result I posted a month or two ago about my byte-code running only 12 times slower than native code for some tests? You won't get that if you burden it with run-time byte-code validity checks, type checking/conversion, parameter checking, etc. -- Chris Gray cg#ami-cg,GraySage.Edmonton.AB.CA </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <ul compact><li><strong>Follow-Ups</strong>: <ul> <li><strong><A NAME="00286" HREF="msg00286.html">[MUD-Dev] Re: Bruce Sterling on Virtual Community goals</A></strong> <ul compact><li><em>From:</em> "Jon A.
