Picaxe Basic Issues

In Picaxe Basic how do I write a piece of code that I only want to execute the first time my main loop runs. For example: I want to get and store an initial value for a sensor and use that later on in my code; however, once I have stored this initial value I don't want the program storing a new value the next time it runs.
