This is probably a little more complicated than what you want, but...
In SWI-Prolog (is that what you are using?) you can do
read_term( Term, [ variable_names( VarDict ) ] )
You can then call your own printing procedure that uses the names from
VarDict whenever it prints variables. I don't see a similar option in
The top level in SWI-Prolog will print your original variable names.
In general, many variables are created during the computation and just
don't have original names.
Hope this helps a little,
