OK. I think I have something to work with now. There are complications with any of the executables that either pause or require a key sequence to terminate early. I don’t know if that is an issue yet.
One strategy that seems to work when setting up the external configuration is to choose “Explore” from the tool name field, find what you’re looking for and then drag it to the field. You end up with the complete path to the executable but that doesn’t seem to be a problem. (I don’t know if that obviates the need for the path in the “Current directory” field or not; not a big deal either way, I guess.)
One suggestion in addition to answering relevant questions from the earlier post, might be to try to figure out how to deliver status and / or error information to the user. I can see this being an increasingly important feature if one were to try to string multiple tools together in a batch.
Thanks again for the hints.
