That sounds like a homework question.


>But what's a T diagram? -John]


A graphical representation of a compiler, and the languages involved
in it:


source language -------------------> target language
                            implementation language


Or shorter


S-T
  I


The name T-diagram comes from the form of the diagram.


The typical homework or exam questions are that you are given some
compilers or interpreters in source form, and some compiler or
interpreter for a different language in executable form, and you have
to find a way to generate some goal compiler or interpreter from
that.
