After years of merging UPC additions/modifications into TXT2MD, I finally
gave up when there was a major update to the SSEC version.   Evidently,
the SSEC version of TXT2MD has at least one bug in it as you have found.
Instead of trying to debug the SSEC routine, I suggest that you use the
Unidata version instead, UPCTXT2MD.  You would run this in exactly the
same way as you did for the SSEC version:

upctxt2md.k buoy.txt 1003 ISHP MISS=-9999

I just did this with your buoy.txt file, and here is the PTLIST listing
for the first 15 records:

So, give UPCTXT2MD a try and let me know how it goes for you.
