This makes more sense to me.

I just logged onto waldo as 'mcidas' and did the following:

cd workdata
mdu.k LIST 1 100  - this showed that the MD files are accessible
ul.k LIST 72469 12

So, from the 'mcidas' account on waldo the data is accessible with no
problems.  The question is why it is not accessible from your OS/2
machine when it has waldo's data disk mounted.  I would suspect that
the REDIRECTions in place when waldo's disk is mounted are incorrect.

Try doing an image load off of waldo using ADDE.  On your slow OS/2 machine
do the following:

DATALOC ADD RTIMAGES WALDO.STCLOUDSTATE.EDU
IMGDISP RTIMAGES/GW-VIS STA=KSTC EU=IMAGE MAG=2

It will be illustrative to compare loading an image accessed by NFS with
one by ADDE transfers.
