Diego,
Thank you for your help.
Yes, I want the scripts to be all in one file in order to execute them
all. But it's nice do execute then individualy (C-c C-c) to test and debug.
I think I have to have 2 blocks of code for each script: one for tangle,
with no <<DEFVARS>> and another to test, with <<DEFVARS>> and <<SCRIPTn>>;
