As moritz already mentioned, that's usually a bad idea. There is a document available which tries to explain that more detailled: Why it's stupid to `use a variable as a variable name` - part 1 Why it's stupid to `use a variable as a variable name` - part 2 Why it's stupid to `use a variable as a variable name` - part 3	[reply]

While brsaravan's answer is correct (and requires `no strict 'refs";` under strict), the usual answer is "don't". Symbolic references are fraught with peril, and usually it's much better to use the hash all the time instead.	[reply] [d/l]

If my understanding is correct (You want to use the hash key as variable name) then you can use `$$key = $value` [download]	[reply] [d/l]
