Programming Praxis

I hate businesses with telephone numbers that spell words; it’s awkward to type letters at a telephone, and often the words are abbreviated or spelled wrong so they are no longer mnemonic, which defeats the purpose. So this morning when I had to call one of those businesses, I wrote a program to translate letters to numbers after I had been waiting on hold long enough to get really annoyed.

Your task is to write a program to translate telephone numbers specified as words. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
