eof in grads

[Diane Stokes]

Dear Suha,

It's possible you didn't add the eofudf entry to your UDF table file (or
create that file if you didn't already have one) and/or you didn't set
environment variable GAUDFT to point to your UDF table file.  In Win2k,
you can set env vars from the Control Panel:
   Control Panel->System->Advanced
