[teqc] helpful tip of week 2030

This week's tip: "no routine" messages in stderr

Buried within the C code that is teqc are over 100 cases that might write out to stderr
a message about "no routine" for whatever is being attempted. (Various past versions
of teqc might have had some of these messages saying "no code" or "no function" or
some other variant, but all such cases should have converged, especially for the
next teqc release, to say "no routine".) Hopefully you've never encountered one of
these messages, but this tip is to try to explain some possible contexts if you do.

No piece of software can do everything and teqc is no exception. The goal is to try to
help you to navigate the complex environment of GNSS constellations, to understand the
signals that the SVs in those constellations broadcast, to read formats that hold the
observables of those signals, to obtain a quality check of the observables, and so on.
But there are obviously plenty of avenues where something "unexpected" can show up. A
"no routine" message attempts to give you at least some information about such a situation.

One of the more likely possibilities is that a manufacturer has added a new record type
in a format that teqc normally reads, but since this new record is probably unknown
to me (the author of teqc), you would get something like:

! Notice ! no routine for <format name> record <record ID> ... skipping

... and hopefully teqc is able to plow through the rest of the file (or stream) and
largely complete its mission. The exception here is if the new record type is where
the manufacturer is now putting all or some of the GNSS observations, or all or some
of the GNSS ephemerides, or all or some of the ancillary site data (like meteorological
observations). If this occurs -- which will require research on your part to determine
what the record is that teqc is telling you about -- then you will almost definitely be
missing something that you otherwise expected.

The above "no routine" message is of the "Notice" type, meaning that the '-notice' or
'+quiet' options will suppress them. (Review messages for notices, warnings, and errors
in tip of the week 1911 https://postal.unavco.org/pipermail/teqc/2016/002134.html.)
Likewise, there are "no routine" messages of the "Warning" type which are suppressed
if using the '-warn' or '+quiet' options. This means that if you're using something
new, like a new receiver type or new firmware, and the unexpected occurs, make sure
you are not using '-notice', '-warn', or '+quiet' so that hopefully teqc can give
you some guidance. And note that the "no routine" messages of the "Error" type should
not be suppressed by these options.

At any rate, hopefully you do not encounter "no routine" messages too often.

Happy teqc-ing!

cheers,
