Thanks all for the replies.
What i want to do is put all compact strings in a hash, so it uses less memory than the 'normal' strings. I have like 2 million of around 50 character strings. I thus want to store these, and convert them to a compact string format. Once all read, i want to loop through each hash key and convert it back to original string format to do comparisons with another string.
In short;
-make string compact and put in hash
-get key of hash, and convert it to original string.
To JavaFan. With vec(), do you mean something like the code below?;
my $input_string = "ACGTCAGA";
$input_string =~ tr
ACGT 0-3;
my $packed_string="";
my $packing_index=0;
foreach (split //, $input_string){
vec( $packed_string, $packing_index++, 2 ) = $_;
}
do you know how i can then convert the $packed_string back to normal readable textstring? So back to original "ACGTCAGA".
