Hello all,

I am interested to get all the keys in the hash of hashes within a particular range. for example:

if I read the first file into hash of hashes as

$hash{$col1}{"$col2_"."$col3"} = "col4\tcol5"
where col stands for the column of the file, then I am interested to search all entries in the hash of hashes which are between range of two values for col2 and col3. col2 and col3 are numeric and col1 is a alpha numeric. I trying to check the entry of the col1 i.e. by
if (exists $hash{$col1}){ if (){ ## Dont know what I should fill here to check the values of col2 a +nd col3 in a particular range } }
Any help in this regard will be highly appreciated. I tried looking some of the examples but I didn't get any.
