Dan,

The problem is that the older, non-ADDE commands need to have more
information specified on their command line in order to correctly access
data in the Y2K capable MD files being created by current versions
(i.e. version 7.5 or 7.6) of McIDAS-XCD.

Try specifying the DAY= keyword using CCYYDDD format (e.g. 1999246)
when trying to run these commands.  Better yet, start using the ADDE
substitute commands, since they are Y2K capable already.

The list of files that will be sunset in the next distribution of McIDAS
(McIDAS-X 7.7 currently slated for release in the summer of 2000) contains
equivalent ADDE functions.  You can look through this list at:

http://www.unidata.ucar.edu/packages/mcidas/mcx/sunset.html

As a example, there are the substitutes for the commands you mention:

old command      ADDE substitute
----------------+---------------
SC               SFCCON
SL               SFCLIST
SP               SFCPLOT
UC               RAOBCON
UP               RAOBPLOT

Again, the old commands are scheduled to be removed from the McIDAS
distribution next summer.

>Thanks in advance!

You are welcome.
