I am trying to create a hash with multiple keys in it. eg. i want to create a hash on sunny,true, 1and count the number of occurences of such a hash. i want to retrive it by hashing on these multiple keys which i dont know how to do.

I create the ahsh in the following manner. 

%hashlist =();

foreach key1,key2,key3

do

$hashlist->{key1,key2,key3}++;

and to list the occurences of such a hash i do,

foreach $key(keys %hashlist)

{

     ($dim1,$dim2,$dim3) = (split %;, $key)[0,1,2];

     print "$hashlist->{dim0} ";

}

and this print the occurences of such multiple keys.

now given a new entry (k1,k2,k3) i want to map it into the hash . how do i do it. i wnat tp know the frequency of k1,k2,k3 . how do i doit. if you can suggest me any other method. It will be of real help to me.

Thanks.
Tanuja.
