Patterns

Hi,

Sorry I can't find a question answering this, I'm almost certain someone else has raised it before.

My problem is that I'm writing some system libraries to run embedded devices. I have commands which can be sent to these devices over radio broadcasts. This can only be done by text. inside the system libraries I have a thread which handles the commands which looks like this

if (value.equals("A") { doCommandA() }
else if (value.equals"B") { doCommandB() } 
else if etc.

The problem is that there are a lot of commands to it will quickly spiral to something out of control. Horrible to look out, painful to debug and mind boggling to understand in a few months time.
