STRDBG: eval an unreferenced field

I searched the archives, and am probably mismembering, but...

I thought there was discussion awhile back about being able to dump
unreferenced fields (those which get the *RNF7031 next to their
names).  Via an enhancement by Hans & Barbara.  We are currently on
V5R2.

I just spent 15 minutes scratching my cranium because I got blanks as
a result of an EVAL in a debug session.  (15 minutes wasted on the
Friday of a holiday weekend is not a good thing.)  The field was a key
field in a file that was just chained to, but because it was not
referenced in the program, I guess the debugger doesn't show the
value.

It seems to me that one of two things should happen.  Either show the
value, even if it isn't referenced, or show a message that states
something similar to CPF7E12 ("Identifier does not exist"), maybe
"Identifier exists, but is unreferenced in the program".  Even though
the former has appeal to me, perhaps the latter is more appropriate. 
At least I would keep more of my hair.

TIA,
Dan
