Hi Jennie-

That's not necessary.   You should upgrade at some point because
there each release contains bugfixes as well as enhancements.

I couldn't find these links in the Site Managers Guide.  Could
you please send me the URL of the page with these links and
I'll pass it on to Robb.

You would only need to download the ldm.tar.Z file.  I'm not sure
why you'd get an error on this download - the links look okay to 
me.  I just tried this and didn't get any errors.

I'd bite off only one upgrade at a time, since the LDM upgrade
isn't critical.  However, you should upgrade it as soon as you
get a chance.

Can't hurt to make a backup copy.

The only things that might be different is that there might be newer
entries for products that have been added to the distribution since
ldm-mcidas-7.4 was released (perhaps FSL2 profiler data). You could
check the output of a listing of your current ROUTE.SYS and the one
that came with the distribution and see if there are any differences.
I'd change the REDIRECTion for ROUTE.SYS in some account other than
mcidas (so you don't screw up the realtime stuff) to point to the one
in the ldm-mcidas-7.6.1 distribution and run ROUTE LIST. Compare that
to a listing from the one you are currently using. If there are no new
products, then don't worry about updating ROUTE.SYS. If there are, you
could add them manually to the realtime version (through the mcidas
account). There is no reason to update SYSKEY.TAB.

I think you have it right.

Using UAPLOT is the better way to go since SKEWT will be sunset.
Also, UAPLOT draws real SkewT diagrams, the ones SkewT draws are
not.

I think you have the right idea.

>Sorry its a long note....but, thats mcidas for you!

No problem.  Better to spell it all out.  Let me know if you have
any problems.
