I would appreciate your comments regarding the following simple interpreter. I would like to grow this into a simple programming language, but before I get...

... Good. So your hash table is, I take it, nothing but an array of pointers to chainable token decriptors, as opposed to an array of token descriptors which...

Hey Rainer, didn't your write some trie stuff once for a spelling checker? Tries are faster, smaller, and more easily expandable than hash tables. Dunno why...
... Yes but not for a spelling checker, and I got the idea from some natural language processing stuff Hamish had written (to help identify geographical origin...

... That gives me an idea that I haven't seen in any language that I know of - modify the parser to insert the name tables as a parsable item so that they...
... I wrote trie and hash test programs, ran them each multiple times, and took the average results. In my implementations, hash tables are smaller and faster...
... You wouldn't be biased, would you? Your trie implementation would seem to have been written deliberately badly. :-) ... I notice that your trie...
