The unfortunate thing is that I will be out of the office starting tomorrow (Wednesday, Sept. 17) until Sunday (Oct. 1). After that, I will be finishing my AMS paper and then preparing for the Policy Committee meeting on October 5-6. Sorry to moan, but I just wanted to let you know why I havn't gotten back to you. Anyway, see below for the small bit of input I can give. >I have a problem with GRDIMAGE. When the source dataset position >is greater than one, the wrong gridfile is used.

Yes, I think you are correct. >Am I doing something wrong??? No, I don't believe that you are. This will merit a more thorough investigation when I get back from trave. Sorry I can't offer more at this time... Tom
