Thank Roderick and John very much to clarify this "exit code 1;" Perl's
stuff to me.
My best wishes.
Att,

1;
All "good" Perl modules have this as the exit code/value at the end.
More specifically, if I may quote from Wikipedia...
# A Perl module must end with a true value or else it is considered not to
# have loaded. By convention this value is usually 1 though it can be
# any true value. A module can end with false to indicate failure but
# this is rarely used and it would instead die() (exit with an error).
