Hello all,

In thinking about legal codes for various columns throughout the Psion 
tables, Karl asked about neighbor codes 997, 998, and 999.  These go 
into the Unkid (unknown ID, not un-kid) column of FPneighbors and 
JPneighbors when an actual sname is not entered.  I have an email from 
the field assistants describing what these codes mean - we had asked 
them about it when we were cleaning up the 99-01 Psion data.  Their answers:

997: not sure whether there is a neighbor near your focal
998: cannot indentify the nearest neighbor
999: we used to use this for no nearest neighbor before we changed it to XXX

So partly this is to document what these codes are, but I also wanted to 
ask about 999.  Since that code became XXX, and XXXs do not go into 
FPneighbors and JPneighbors, does anyone see any reason not to delete 
all 999s from FPneighbors and JPneighbors?  There aren't that many 
currently, compared to 997 and 998.

Daphne (Karl, please note correct spelling...)
