Problem:
   I am getting an error F6419: illegal structure for
unformatted file.

Response:
   There are two likely possibilities for this error
message:

   1. Examine the OPEN statement for the file. You may have
tried to do an unformatted READ on a formatted file. Since
formatted files do not contain the length information that
is required in unformatted files, this error would occur.
   2. Do not assume that since the notion of a file being
UNFORMATTED is part of the ANSI FORTRAN standard, such
files created on one machine are transportable to any other
machine. The contents of such files are nonstandard and
completely up to the implementor. Any data files that you
wish to transport between machines should be produced only
by FORMATTED WRITEs.
