In another part of the code there is a variable sanitize_mode which
>can have values between 0 and 4 to denote different treatment for
sanitising file and directory names, and I haven't worked out how that
gets set.
$sanitize_mode is set at the start of substitute() from the second
parameter to that function, with a default of 0 if that either doesn't
exist, e.g. substitute('foo'), or is the value `undef'.
I think the call where it's passed as 1 is
# Don't create subdir if we are only testing recordings
# Create a subdir for programme sorting option
elsif ( $opt->{subdir} ) {
my $subdir = $prog->substitute( $opt->{subdirformat} || '<longname>',
1 );
Aside from my previous reply where I said I had missed the fact that the OP
was concerned with –subdir, I think I did eventually get that. The
function/procedure/subroutine parameters I have difficulty with are ones of
the form
my $string = shift;
I am inclined to agree with MrBrightside's comment in stackoverflow.

"Forgive me but this seems like the worst convention ever for code
readability."
