I have seen no other problems with GRDDISP. Yes, you do need to, but I ran a copy of GRDDISP linked against a mcgget.for compiled with no optimization, so the problem is likely to be somewhere else. >>From address@hidden Mon Nov 22 15:11:56 1999 > >I did some testing.

OK, thanks for adding this information. I am creating an inquiry at SSEC about this right now. Sorry for the problems. Tom
