I am not able to answer this question, please ask it to Claude Gomez
who wrote this document.

If you have Scilab-4.0 installed you can play with it. The
preliminary version of Scilab2tree is named macr2tree.
here is very simple example of use
-->function y=foo(x)
--> y=x+1
-->endfunction
-->t=macr2tree(foo)
It returns the full abstract syntax tree coded by a hierarchical
structure of tlists and lists Scilab objects. To get a more readable
display and also to illustrate how Scilab can deal with such a
structure, I give you below a file of scilab functions for display
overloading. If this file is loaded into Scilab
--> exec %program_p.sci;
The display of the t structure above become
-->t
t =
Program
Name : foo
Outputs: y
Inputs : x
Statements
<EOL>
Equal
Expression:
Operation
Operands:
x
1
Operator: +
EndOperation
Lhs :
y
EndEqual
<EOL>
Funcall : return
#lhs : 0
Rhs :
<empty>
EndFuncall
<EOL>
EndProgram
These functions work with your testscilab function too (but select
case constructs are not yet handled). Just try it and look at the
comment for the structure explanation
