If the CM Work Area is not set, I suggest adding a warning message for uses who are trying to do a Get Copy operation stating something similar to:
"Your CM Work Area is not set. Unexpected results may happen if you continue."
And instead of showing the ugly error in the attached screenshot, an error stating the need to specify a valid CM Work Area would do the user a lot more good than an error saying:
"FSY0004610E Error: Cannot open file..."
"NCL4501194E Error: failure closing file..."
If there was a hyperlink to the CM Work Area documentation in the messages, that would be a plus.
