If I place without warning at the top of a program
no warning message appear when the program.
If I place without warning at the top of a program
and AFTER I have a list of bunch of local constants;
After the constants are defined I place a
with warning.
Then when I end my program I get a
message list of unused local constants.
In other words without/with warning will not
hide the constants.
That is not the way that with/without should work.

Maybe try putting "without warning" at the end
of the file that has the constants. Euphoria doesn't
issue any warnings against those constants until
it is certain that they will never be used. For local symbols,
that happens at the end of the file, and the internal
flag for "warnings on/off" is used at that moment
to decide whether to issue warning messages.
The "without warning" status should then revert back to what
it was in the main program before that file was included.
Included files do not affect the warning status of the files
that include them.

So, is without warning executed at compile time (traslation to il) or at
execution time? At what point are the warnings issued?

Warning messages are created at compile-time only,
but they do not appear on the screen until the interpreter
(or translator or binder) has finished compiling/executing your program.
If "without warning" is in effect at the time that
a warning situation is detected, the warning will be suppressed.
In Bernie's case, the fact that a symbol is never used
cannot be detected when the symbol is declared, but only at
the end of that symbol's scope. So it might not be obvious
how you would suppress that specific warning.
