Q: Is it possible to fax something to an e-mail account?
A: No. It is not possible. This myth got started when some e-mail accounts allow you to pay for an additional fax receive number or voicemail receive number where the incoming message or fax are included as an "attachment" and accessible via your e-mail inbox. It is something known as "universal inbox". However, it is NOT a widespread feature. The e-mail provider must explicitly provide this feature, and the number cost extra.

Q: Is it possible for a function in a programming language to return multiple values?
A: No. By definition, a "function" in a programming language returns only ONE value. You can "fudge" it by combining the separate values into a "composite" value, such as an array, or a struct/custom type, or such, but it really is returning a single value. You will have to de-couple the values outside the function.
