I have an array block_list :
push ( @block_list ,$word); # this word is read from a file.
$list_name = $block_list[$#block_list]; # i extract the last element
ie $word in this case
now i want to define an array with the name $list_name
like ,
my @"$list_name";
But this is giving me errors...
It can be done, but is not recommended. Consider this solution instead:
my $word = 'Perl';
my %lists; # declare a HoA
push @{ $lists{$word} }, $word;
print @{ $lists{Perl} }, "\n"; # prints 'Perl'
You may want to read the FAQ entry
perldoc -q "variable name"
about why what you tried to do is not recommended.
