Careful. You tested the PRINT command, and I agree that "it" never
automatically retrieved environment variables.
On the other hand, OPEN has always expanded shell variables, for as
long as I have known. And my experience is that shell variable
expansion by OPEN still works within IDL 8.1.

and it just tells:

I don't remember that it ever worked without using getenv function.

I don't use the Workbench, I'm not sure why it wouldn't pick up
environment variables. ITT VIS did change the way the processes for the
Workbench and IDL were managed in IDL 8.0, so maybe that could be
responsible?

Thank you, Mike. Any idea why my original code worked under IDL7 and
does not under IDL8? I appreciate your help. Barry

You could add a line in your startup file to add this. For example, if
you don't already have a startup file, create a file, say
my_startup.pro, with something like:
setenv, 'SEADAS=/Volumes/1TBSATDATA/sw/seadas6.2'
If you don't already have a startup file, then you will need to do:
IDL> pref_set, 'IDL_STARTUP', '/path/to/my_startup.pro', /commit
This will tell IDL to execute the commands in the startup file every
time IDL launches (from either the command line or the Workbench).

You could add a line in your startup file to add this. For example, if
you don't already have a startup file, create a file, say
my_startup.pro, with something like:
setenv, 'SEADAS=/Volumes/1TBSATDATA/sw/seadas6.2'
If you don't already have a startup file, then you will need to do:
IDL> pref_set, 'IDL_STARTUP', '/path/to/my_startup.pro', /commit
This will tell IDL to execute the commands in the startup file every
time IDL launches (from either the command line or the Workbench).

Thanks, Mike. I think your suggestion narrows down the problem. When
I invoke IDL from a shell session, like you did, I get the following:
bash-3.2$ idl
IDL Version 8.0.1, Mac OS X (darwin x86_64 m64). (c) 2010, ITT Visual
Information Solutions
Installation number: 230343.
Licensed for use by: Computer Sciences Corporation
IDL> PRINT, getenv('SEADAS')
/Volumes/1TBSATDATA/sw/seadas6.2
IDL>
which is correct. However, I was working from within the IDL
development environment (MacOS10.6.7) and this is the result there:
IDL Version 8.0.1, Mac OS X (darwin x86_64 m64). (c) 2010, ITT Visual
Information Solutions
Installation number: 230343.
Licensed for use by: Computer Sciences Corporation
IDL> PRINT, getenv('SEADAS')
IDL>
which isn't correct. I may need to add something (not sure what) to a
start-up script somewhere.

Check the value of the SEADAS environment variable with the GETENV
routine. Everything seems fine for me:
$ export MIKE=Hello
$ idl
