Hi Chris-

There are now! ;-) see below.

They should see the decoding messages after this. Something like:

M0NIDSDC -- BEGIN
PRODUCT CODE=R5       5    001640
M0NIDSDC -- DONE  AREA   483

They can check the status of the decoder by typing:

DECINFO LIST DMNIDS

if it lists as inactive, they can activate it by typing:

DECINFO SET DMNIDS ACTIVE

It shouldn't automatically deactivate, so if it is inactive, then
I'm not sure how it would get that way.

The changes to the NLDN datastream should not have affected the OS/2 
decoder since it does not use the LDM header information to get the date
and time.  I haven't been feeding NLDN to my OS/2 box, but I just
started it up and it seems to work, however there are no lightning 
flashes since 12Z so I can't really verify this.

That's my guess, but....

I just noticed on my OS/2 machine that the dates in the NIDS AREA files
are coming out as 5 instead of 100005. I was able to create a new binary
of the decoder on my OS/2 system (tested briefly) and I've put this new
version of the decoder (dmnids.exe) in the os2/750/bugfix directory of
the McIDAS FTP account. You could install this version of DMNIDS in
c:\mcidas\user\code, deactivate the decoder and then reactivate it to
get the new binary:

from the OS/2 command prompt (assuming McIDAS executables are on C:):

c:
cd \mcidas\user\code
ftp ftp.unidata.ucar.edu
(login using umcidas/XXXXXX)
cd os2/750/bugfix
bin
get dmnids.exe
quit

in McIDAS:

DECINFO SET DMNIDS INACTIVE
DECINFO SET DMNIDS ACTIVE

Note, after the AMS meeting next week, my OS/2 system will become a
Windows NT system, so I will not be able to solve future OS/2 problems
that require code changes.  If SIU wants to continue running McIDAS,
they will have to move over to McIDAS-X.

Thanks.

I'm downloading 7.60 for UNIX right now.  We'll see if I can get it
running remotely.  ..Chris..
