wierd. the line shouldn't start with "|" either.

what does the command line look like?
are you feeding postions from stdin or a file?
does setting null= to something other than * make it 
  "|NaN9.6|897|24.1" or "|NaN6|897|24.1"?
what computer platform? (ie newline problem)
  if this is cygwin, could you open with TextPad? (www.textpad.com)
  if this is mac, could you open & view with bbedit or nedit from fink?
what does a good data line look like? (ie querying one or two maps?)

looks to me like a bug -- the "79" of "799.6" gets over written by a
return without a newline and then the final queried value ("|*").
