Hi Rita,

>McIDAS 2002.  

Since I have not released the Unidata version of V2002, you must be using
the SSEC one.  The solution to your problem is listed at the end of this
email.

SSEC McIDAS-X V2002 already has a Fastrack addendum.  The reason for the
addendum -- as listed in the documentation for the Fastrack Software
Changes:

http://www.ssec.wisc.edu/mug/changes2002a.txt

is:

     Modules released 10-JUN-02 in version 2002a
     -------------------------------------------
11739 imgremap.pgm 1.74       TRACE=1 was inadvertently left in the 
                              code, which was causing a 'trce' 
                              file to grow in user accounts 
                              running IMGREMAP. The 'trce' file is 
                              no longer being automatically created by 
                              IMGREMAP.

So, I am guessing that your user is using the IMGREMAP command, and you
are running the SSEC V2002 release without the addendum.  The solution
is to download the incremental update to V2002 or the rerelease of
V2002 and install the mods or rebuild the entire distribution.

Please let me know if the problem you user found is not the one that
has already been caught and fixed!  Thanks...

>Thanks for all the help,

No worries.

Thanks again,

I really appreciate the patience and help...
I guess it would have been easier not to debug,
and to have just waited!  However, I always
start with my configuration first. I would rather
find my mistakes myself!

Thanks again,
Rita
