Don't bother trying to use any feedtype other than IDS|DDPLUS; the
NOAAPORT ingester that generates these products from the textual
channel sets all of those bits regardless of the actual data-
product (it has no choice).

I'm not sure what you're trying to do, exactly, but the pattern
"^...... (C|P|(K[^WN]|KW([^A]|A[^L])|KN([^C]|C[^F])))"  will
select all products whose country-code starts with a C, P, or K
except for KWAL and KNCF.

> Can you help? I'll take any and thank you in advance for any help!
