+      resource module (the last in listing by command po) to resolve 
+      constant names. 
       N.B. You need the flag -retain when importing the grammar, if you want 
       the oper definitions to be retained after compilation; otherwise this
       command does not expand oper constants.

       and hence not a valid input to a Tree-demanding command.
