James Kelly from here and Tom Whittaker have been mucking
around with adding Text support to the text file loader (it currently
only supports RealTypes, they are adding TextType).

  I found that running a demo in jython (see Toms email 29 Jan 2001)
doesn't work very well with the experimental text support.

  Part of the problem is that visad.ss.MappingDialog does not have the
text types displayed.  This is due to what seems to be a fault in
visad.util.DataUtility.parseScalar() which really only parses
RealTypes.  I can fix this, but then MappingDialog falls over.

  It all starting looking bad, so I stopped.  It's possible that
TextType support is a bit thin in some areas.  Is this worth fixing?
(we at BoM would like it working :)

jython spits out this straight away:

java.lang.ClassCastException: visad.TextType
        at visad.ss.SSCellImpl.doAction(SSCellImpl.java:170)
        at visad.ActionImpl.run(ActionImpl.java:228)
        at visad.util.ThreadPool$ThreadMinnow.run(ThreadPool.java:92)

And if I click on Mapping I get:
Exception occurred during event dispatching:
