Robert,

OK, good.

OK, I verified that this one works.

OK, I verified that this fails.

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.

This sounds like a problem that needs to be reported to SSEC; I will do
so.

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

Sorry for the problems.
