Question

I tried this

contract MyContract{ bytes public data = 0x3333; function clearData(){ data = 0x; } }

But solc doesn't like me trying to set data to 0x

Use "".

contract MyContract{ bytes public data = "0x3333"; bytes public empty; function clearData(){ data = ""; } }

Tested using https://ethereum.github.io/browser-solidity by looking at the value of data and empty.
