Have you already tried accessing them as described here:

Hi Michal,
Basically we have our own actor that we use to execute commands either
locally or remotely using our own tools (Nimrod/G and Nimrod/K). The
problem is in those actors when I try to evaluate the expression which has
environment variable in it that is not part of the regular set (PATH, HOME
etc). Is there some way I can evaluate them programatically?
I had to change the code so that the parameter mode is set to lazy
(command.setLazy(true)) because we try to build the environment from
incoming ports and such. If I could load the environment variable list and
parse it myself in the code I would do it. So do you have any idea how to
access it in code?
Thanks in advance for your answers,
Slavisa

That works fine. Can we use this somehow in External Execution actors? I
tried and failed.
What we need is a way to use environment variables to locate executables,
e.g. FSLDIR=/opt/local/bet, so that I can execute $FSLDIR/bin/bet. I
understand that if added to PATH these will be accessible by simply by
executing 'bet' but we'd still like to have access to environment
variables
to locate specific versions etc.

Try following instead.
Inside expression actor use following:
getenv("YOUR_VARIABLE_GOES_HERE")

Hi,
Could someone explain to me if there is a bug or I am doing something
wrong
that my workflows can't access environment variables.
I tried setting them up in usual ways (profile scripts) and by using
environment.txt but no actor has access to them.
For example I tried setting up TESTVAR and then accessing it in constant
actor but it raises an error as if it was not there. Top of the
exception
stack is just below.

PS. I can see this being set with kepler-2.4.0/module-info/
environment.txt
when Kepler is launched by kepler.sh and I get messages such as
....
Set environment variable: TESTVAR = mymessage
Set environment variable: R_HOME = /Library/Frameworks/R.
framework/Resources
....
