How to show result of a function call?

I'm writing some oracle functions and want to call them and display the result.
Is there an easy way to do this in oracle? Up to this point I've written a little pl/sql routine to do it where I declare a bind variable, assign it to the function result, and print the variable, but would like a simpler way, like a 1-line select statement. Any suggestions?

Thanks,
Daniel
