No, you don't want to do that. Suppose the string in your text file is INC
or ISA. You'll trash those global arrays, or perhaps other arrays in your
script.
Use a hash to hold these arrays instead. The hash keys can be the names from
your file. Then you're safe.
my %h;
if ($line=~(/^\[\[(\w+)\]\]/)){
$h{$1} = []; # initalize to an empty array
}
