Yes.

Yes, beautifully expressed.

Yes, but my current solution brakes on crossing the path of C code : I use
\gobbleinput that is defined as (according to some documentation) :
\def\gobbleuntil#1%
{\long\def\next##1#1{}\next}
As I understand this code, the "goblling" is made as enclosing the text that
you dan't want to be added to the output as the body of a function.
If the text contains some restricted characters as the "%", this proposition
brakes.

This is what I've made : I express a list of numbered slides and check if each
slide has to be outputted or not into the final document.

This is the path I've followed so far with success for some of my lectures.
But, when I've applied the same process to slides containing C code, this
process brakes.
I've tried yesterday evening to modify my slide definition to use the solution
provided by Luigi, but I've failed.

How do you make this ?
Please save my remaining hairs on my head !

Thank you very much for sparing some time to express so efficiently my problem.
best regards,
