[gradsusr] gxout print

[Jeff Duda]

Alright, I think I see one problem with your Grads code.  set prnopts is
only effective when gxout print is used.  When you use gxout fwrite, your
data are being written to a binary file called dls.txt rather than an ascii
file called dls.txt.  Try changing the graphics output to print and see if
you get the results you are looking for.
