in reply to variable number of hash of hashes

Hello,

Be careful with your code:

1. %hash{'string1'}{'string2'}{'string3'}{'string4'}++;
2. %hash{'string3'}{'string4'}++;
3. %hash{'string1'}{'string2'}{'string3'}++;

In 1 you are defining {'string1'}{'string2'}{'string3'} with a hash, and in 3 you want to add 1 to that hash ... which is not that you want

Use a final string like "n" or "count", like GrandFather propose:

1. $hash{'string1'}{'string2'}{'string3'}{'string4'}{n}++;
2. $hash{'string3'}{'string4'}{n}++;
3. $hash{'string1'}{'string2'}{'string3'}{n}++;
