Larry,
excuse me for loving ASCII format.
But i think you should consider the utility of the ascii format and don't
abandon it.
A good binary header even if will be good in the very sense of the word (as
without doubt PSN4 is)
is always limited to his structure. The power of popular software like
Excel, Access an so on (mathlab)
is that they can treat any kind of ascii files using a programmable record
separator and a field separator.
Windows too uses the INI files that are always ASCII. In the majority of the
cases using
ascii file you can add and remove a field without losing the compatibility
with higher and lower versions.
I'm planning (with my 6smowin datalogger) to build an ascii programmable
format with definitions
on where you want have any field in the header and how the field will be
setup by the event generator.
One Italian researcher of the Italian Seismic Service suggested to have all
files in ASCII with ONE line
of header (in ascii too) with formatted text or with a field separator.
This beacause all softwares used by universities are prepared to read one
single line of header with formatted
fields, always in ascii.
If i'm not in wrong, Mars Light station, removed the use of the header! The
out only with a RAW Ascii file!
So, sorry to make these considerations in the mailinglist, but i think they
will be usefuls to others that are
considering  to write some kinds of dataloggers.
You said, ascii format is not official, i'm saying: this non officiality is
its power!
Warmly
Mauro
