Those utc1, ..., utc12 etc inspire a suggestion: a mild addition to the
syntax to allow specifying that the following repeat count should be
interpreted as the expected dimension of a tuple (unpack) or any
indexable object with a __len__ method (pack):
(top, ip, messageCounter, ackRequired,
dataType, utc, st, numberOfLabels, dataWord,
) = struct.unpack("! H /4B H B B /12B /6B H I", strMessage)
Apropos of a recent thread: I don't need pointing at the suggestion box
and the patch submission gizmoid on Sourceforge -- I'd be happy to do a
patch, just wondering if anybody's interested in having that, besides
me and Pat Malone :-)
Cheers,
John
