Hi Tim,
According to the documents, it should be supported in a standard way as you mentioned.=

I think you already followed the instructions provided at
"The env-var element, if present, contains the environemnt to be passed to the Shell command.
should contain only one pair of environment variable and value. If the pair contains the variable
such as $PATH, it should follow the Unix convention such as PATH=3D$PATH:mypath"

How did you invoke the executable?
Can you pls include your related wf.xml section?

Thanks Mona. I was able to get it to work this way, though it is less
than ideal.
