Josh,

Sorry I couldn't respond to these sooner, but I have been out of town
since Wednesday morning.

Since the MCGUI continues to function correctly for the user 'mcidas', it
means that the System Key Table setting #15 is set correctly.  The fact
that the MAP MCOL= invocation run by the MCGUI is failing from the
user account, it must mean that the copy of SYSKEY.TAB that the user
account is pointing at is different from the one that the user 'mcidas'
is pointing at.  We can ascertain whether or not this is true by you
running the following from both the 'mcidas' and 'user' accounts:

DMAP SYSKEY.TAB

If the user account is pointing to a different copy than the 'mcidas'
account, and if the user account _can_ point at the copy that the
'mcidas' account is pointing to (i.e., the user account has access to
the data directory, /var/data/mcidas (or is it in /var/data/xcd?) in
your case), you need to change where the user account is looking for
SYSKEY.TAB.  For instance, you could set a file REDIRECTion in the
user's McIDAS-X session by running:

REDIRECT ADD SYSKEY.TAB "/var/data/mcidas

If the DMAP SYSKEY.TAB listing shows that both the user and 'mcidas'
accounts are pointing to the same copy of SYSKEY.TAB, it means that the
user account can not read SYSKEY.TAB.  While a general user account
should never be able to write to SYSKEY.TAB, it always needs to be able
to read SYSKEY.TAB.

Please check the stuff above.  In one way or another, the user account
is not able to read the SYSKEY.TAB file that was updated by 'mcidas' from
the SYSVAL CHANGE 15 1 invocation.
