I find I'm undefining variables my assigning an
unitialized variable to defined value to make it
undefined (as exemplified below).
Is there a better way to do this?
my $k;
for($i = 0; $i < $c; $i++){
if ( defined $k ){
print $x[$k];
my $t; # intentionally undefined
$k = $t; # undefine $k
} else {
$k = $i;
}
}
