Chad,

This sounds good.  Perhaps it would be wise to schedule this mod
at the same time that the MD, GRID, and TEXT products are to be
dropped from the Unidata-Wisconsin datastream.  We are hoping that
this will be effective on July 1.

                       ^____  7.6 :-)

                     ^____  7.6 :-)

Right, we did talk about this.

>Is there any logistics preventing us from doing this, such as OS/2 sites,
>McIDAS Routing etc?

The McIDAS routing procedure (which gives user an "event" scheduler) is
the sticking point.  I have to develop a new way of doing this before
I can change the form of the data in the stream.

>Do you know if there are problems running the LDM on Solaris 2.7?

We have not upgraded our LDM machine to 2.7 yet.  I believe that we
are scheduled to do the upgrade coming up fairly soon, however.  I can
get back to you with comments on 2.7/LDM after we do this.
