Re: evaluator

[Paul Kienzle]

The evaluator is built into the node classes of the parse tree.

You can find the root invocation in the function eval_string
in parse.y.  The root node is a tree_statement_list as defined
in pt-stmt.h.  eval_string calls the eval method of the
tree_statement_list.

The whole point of the compiler is to translate the parse tree
into C++ statements, not to call the octave evaluator.  The
simplification in the first pass is that you will be using
arithmetic on octave values rather than type inference.
