in thread Clear / Initialize multiple hashes

but later on if I want to clear all of them how should I go about it?

The simplest way is to scope them such that they get reinitialised by re-entering the scope each time you want to re-use them:

for( some loop condition or contruct ) { my( %hash1, %hash2, %hash3 ); ## do stuff with them ... }

Each time that loop iterates, the hashes will be reinitialised for you.

But, it you really need to do it manually, you could use:

undef %$_ for \(%h1,%h2,%h3);
