Can you add new global variables or is it picking the environment variables up from the execution environment? i.e. could I specify $fred? You can share input values between processors in Taverna by setting a String Constant, but that would not pick up the environment variable. I'll add the default value request into Jira (the bug tracking system). > Thanks. > > Roger Alan ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
