Well... the names of the output files might have that pattern, but I can guarantee that pqact(1) doesn't understand those patterns. If you search the relevant pqact(1) configuration-file(s), you'll likely see that the string "YYYYMMDDHH" doesn't appear as the name of a file in a FILE action. It's possible, however, that such strings are used as input to various GEMPAK decoders -- to tell them how to name their output files. > I guess they work because I’ve been using them for years in our pqact files. > > And a clarification please: > The (\x: ..) in the documentation will always be the number referencing the > day-of-month parenthetical? And the yyyy and mm will be derived from it? That's correct. A WMO header doesn't have a year field -- so a heuristic is needed to determine the year when near the end of one year and the beginning of the next.
