The last time I added a field to the UNaXcess userfile I added a ":%s" to
the fprintf() write and a "getfld(buf,var)" to the read.  Trivial.  And
because of the way getfld() is written and the fact that new fields always
go at the end of the line (record), the userfile is self-upgrading:  if the
field is missing, a default value is used and the field is added on output.
Try THAT with a binary file!

As for newlines in "records", etc.:  there is a backslash-escape convention
that deals with this quite well.  But I rarely, if ever, find a need to
store newlines in data records.
