obviously ! but if the error message is inacurate, how could i find the error ?

This is surprising but this can explains a lot of things.
How did you figure that ?

At least the linear version is a good start, but a "template" for
recursive functions would be a good start. It's not a high priority, though.

Thank you for your help !
I quickly looked at the new code and it seems to be ok.
i'll have to update my "stable" tree and the HOWTO.

Other tasks before i do a 0.1 version :
 - clear up ALL the licence issues. I met Mélanie Clément Fontaine
   today, who explained me a few things.
 - add the INC unit : I found an old "MR" version in the archive and
   now i have enough VHDL skills to understand it :-)
 - find a way to integrate the manual in the source tree.

Any request/remark/idea/suggestion ?...
