Very good.

Hmm... the output above may be self-contradictory; we need to run a test
to find out:

- please make sure that no 'mcenv' instance is running before re-running
  the test above.  The easiest way to do this is to logoff and then
  log back on, and then run 'env' from a 'mcenv'-created shell.

The thing that is contradictory to me is illustrated by the MCPATH and
MCENV_POSUC values above:

MCPATH=/home/mcidas/workdata:/home/mcidas/workdata:/home/mcidas/data:/home/mcidas/help
MCENV_POSUC=4456458

If the instance of 'mcenv' created the shell (environment), then MCPATH should 
look
like:

before running 'mcenv'

MCPATH=/home/mcidas/workdata:/home/mcidas/workdata:/home/mcidas/data:/home/mcidas/help
MCENV_POSUC -- undefined

after running 'mcenv'

MCPATH=/home/mcidas/workdata:/home/mcidas/workdata:/home/mcidas/data:/home/mcidas/help:/home/mcidas/.mctmp/4456458
MCENV_POSUC=4456458

The fact that /home/mcidas/.mctmp/4456458 was not added to the end of MCPATH
indicates that 'mcenv' did not modify MCPATH like it should.  The fact that
MCENV_POSUC is define says that some instance of 'mcenv' did run.

I would understand if you were running in the C Shell, but since you are running
in BASH, I am left scratching my head.  The reason?  When running in the C
Shell, .cshrc gets read when 'mcenv' runs (sourced).  This is the reason
that the method I recommend for setting the McIDAS environment for the user
'mcidas' has one _not_ define environment variables directly.  Rather, I
suggest that one sources a file from the McIDAS distribution to set needed
environment variables.  This process is described in the Unidata McIDAS
Users Guide:

OK, it is just the name of the Ubuntu release.  No problem...

By the way, if we can't resolve things through the back and forth email 
exchanges,
I am happy to logon to your machine and check things out.  To do this, I would
need the login information for the 'mcidas' account sent to my private email
address, address@hidden, in the following way:  one email with the
name of your machine and another email with the password for the 'mcidas'
account.  Each email should _NOT_ reference information in the other email
(i.e., don't include the user name or password in the same email as which
machine they are valid for).


Cheers,

Tom
