No longer need help!
This smells a lot like a homework question.
Regardless, this is pretty vague. Pico is simply a text editor, it doesn't run programs. What code have you already written? What language? I realize you're pretty new, and that's OK, but this is like knowing nothing about flying a plane and asking "ok, so I'm at the controls and I'm in the air what does this needle thing do?"
Found out how to do it, thanks again.!
It's good form to include your solutions so that others may learn from your examples.
