When the /LF switch is used (to create an LSX list file), unreferenced variables are now listed at the end, as a convenience for those interested in clearing dead weight out of program. Note, however, that these are not errors, and in many cases, it isn't even desirable to remove them. For example, it is common to group misc variables under a heading, e.g.
MAP1 WORK'VARS
MAP2 X,F
etc.
Typically in the above case, there would probably be no explicit reference to WORK'VARS, but you couldn't just delete it without elevating the MAP2 variables beneath it to MAP1. So the new feature is only to be used a guide (or ignored) as you see fit.
