Hi Ted. "-c" or "--symmetric" encrypts with a symmetric key that is
derived from a passphrase. No public key is used. Because of that,
using "gpg -c some_file" will ask for a passphrase, and that passphrase
must be used when you want to decrypt the file.
But when you specify "-e" or "--encrypt", GnuPG will use a public key to
encrypt the file, and a recipient's public key must be specified. This
means that when you specify both "-c" and "-e", you will get a file that
is encrypted by a symmetric key and a public key. That is why GnuPG is
asking for a recipient.
