Hi Francisco,

The McIDAS server command 'mcenv' does a number of things when it runs: create
shared memory that McIDAS commands will use; setup some McIDAS environment
variable values; and creates a new shell.  It is not surprising that you
don't see anything after running 'mcenv', but we need to make sure that the
'mcenv' you are running is the one in McIDAS.  Please do the following
and report the results back:

<login as 'mcidas'>
cd $MCDATA
which mcenv

This will tell us which 'mcenv' is running (other packages might have an
executable also named 'mcenv').  If the copy of 'mcenv' that would be run
is not the one from McIDAS, you will need to adjust your PATH to make sure
that the directory in which the McIDAS executables are stored is first
in the PATH.

If the McIDAS version of 'mcenv' is the one that is run, please do the 
following:

which mcenv
mcenv
env

The 'env' will list out the value of all environment variables.  Since the 
McIDAS
'mcenv' will modify the environment variable MCPATH to add the ~/.mctmp/<shared 
memory id>
directory to the end, we should see if it is working by examining its value
after running 'mcenv'.

By the way, I am not sure what you mean by your reference to 'Lucid'.  Can you 
explain
this further?

Cheers,

Tom
