Interpreter. What is the best way ?

      I'm not sure if this is a question that really fits here, but I am have
started to write an application extension language, that combines aspects
of C and PASCAL (ie. it should be easy for either kind of programmer to
pick up on, even though it will be a subset.)


      This language will be interpreted, and herein lies the question. For
this kind of system, is it better to compile the program into bytecode,
into a parse tree (like gawk), or into tokenised input ? Obviously,
interpreting the sources directly is NOT the quickest way of doing things.


      I should also note that I want to be able to include this language into
various applications, and want it to be easily extensible. For example, in
order to register an new function (in the source) I just want to add a
declaraction to a table.


      If anyone has any comments, please post to the net, or email me. I will
summarise.


    Thanks in advance.
