When you return a value from a subroutine, you should
'catch' it in a variable, or use it outright:
my $myname = myname();
# or
print myname(), "\n";
A
return token is really quite optional - Perl will
return the last value evaluated, so:
sub myname {
my $name = "bill";
}
will return 'bill.' As for your second example - $myname
is declared outside of sub myname - but it is accessible
by myname(). It works because you defined $myname, unlike
you did in the first example.
The best way to deal with this is like so:
my $myname = myname();
print "my name is $myname\n";
sub myname {
my $name = "bill"; # notice subtle change in variable name
return $name; # not necessary, $myname works too
} # but it is not the same $myname ;)
