Geoff is 100% correct. You may be able to get away with cat-ing .r00,
.t00, or .t01 files together, but it is _not_ a recommended procedure by
Trimble and sooner or later it will bite you. Cat-ing .dat files _is_
safe. Another procedure is to let runpkr00 "merge" a bunch of .r00,
.t00, or .t01 files together into a single .dat (.mes, etc.) file by
creating a list of the input .r00/.t00/.t01 files. At UNAVCO, we have
a bunch of permanent stations where the raw data arrive as sub-daily
.r00, .t00, or .t01 files. runpkr00 is used to merge these into a single
daily .dat file which is what we archive and what we (using teqc) translate
into the RINEX files that go into our public ftp area.
