[gradsusr] Use of ^ Character in Descriptor File

Sephen,

   In the past "^" expansion worked on windows, but since I am not a
windows user I have to rely on users to report such problems.  In fact, the
model.ctl that I use for tests has "^" in it and all windows builds passes
100% of the tests.

   Can you send me the full name of the directory where the data resides? I
want to make sure there is no glitch with the handling of specific
directory names when expanding "^". Please send me the 2 versions of the
ctl file: one with the "^" and the other with full pathname and I will take
a look.

   Arlindo
