Hi Jeff,
At the risk of sparking a minor controversy, I'd suggest the use-case for doing something "just in a paragraph" is fairly slim - it's pure legacy. Many other tools exist that give you a much more flexible and colourful palette for running, logging and controlling jobs, why not use a Basic program at least?
However, you could get what you want by using <<F...>> to retrieve the value from a previously updated control file.
Regards,
Stuart
