Re: Compilation Errors

Try replacing the TestArea.java in your visad\data\mcidas
directory with the attached file, and compiling again.

Cheers,
Bill

/** This will test the Area File Adapter and Base Map (McIDAS

 *
 *  At this point, only GVAR, MSAT and MOLL navigation is supported, and no

 *  There is quite a bit of extra printout that is usually
 *  commented out, but may provide some insight into the
