I don't think you are correct on this one Michael - by definition a field must be referenced in order to pass through a program. It cannot appear in a call to another program without that counting as a reference. That in turn means that it would have to appear in linkage - which is a reference in its own right.

If it is passed to the program and does not appear in linkage you are correct - you would not be able to see it.

It can be a little deceptive as data can be received and passed through
these variables when calling another program, but if they aren't
referenced in your program you can't see it when debugging--although the
data is really there.
