There are a few subtleties I think. First, I don't think we save a copy of the dictionary that corresponds to the active file. We'd need to do so, and then restore it for CLEAR TRANSFORMATIONS. Second, some transformations are not exposed to the user and should not be cleared. The specific one I have in mind is the DESCRIPTIVES transformation that produces Z scores. As far as the user is concerned that transformation doesn't exist so it shouldn't be cleared. That's all that comes to mind at the moment. -- Ben Pfaff http://benpfaff.org _______________________________________________ pspp-dev mailing list [email protected] http://lists.gnu.org/mailman/listinfo/pspp-dev
