-----------------------------------------------------------------------
-Statistical procedures:
-
-For each case we read from the input program:
-
-1. Execute permanent transformations.  If these drop the case, stop.
-2. N OF CASES.  If we have already written N cases, stop.
-3. Write case to replacement active file.
-4. Execute temporary transformations.  If these drop the case, stop.
-5. Post-TEMPORARY N OF CASES.  If we have already analyzed N cases, stop.
-6. FILTER.  If this drops the case, stop.
-7. Pass case to procedure.
-
-Ugly cases:
-
-LAG records cases in step 3.
-
-AGGREGATE: When output goes to an external file, this is just an ordinary
-procedure.  When output goes to the active file, step 3 should be skipped,
-because AGGREGATE creates its own case sink and writes to it in step 7.  Also,
-TEMPORARY has no effect and we just cancel it.  Regardless of direction of
-output, we should not implement AGGREGATE through a transformation because that
-will fail to honor FILTER, N OF CASES.
-
-ADD FILES: Essentially an input program.  It silently cancels unclosed LOOPs
-and DO IFs.  If the active file is used for input, then runs EXECUTE (if there
-are any transformations) and then steals vfm_source and encapsulates it.  If
-the active file is not used for input, then it cancels all the transformations
-and deletes the original active file.
-
-CASESTOVARS: ???
-
-FLIP:
-
-MATCH FILES: Similar to AGGREGATE.  This is a procedure.  When the active file
-is used for input, it reads the active file; otherwise, it just cancels all the
-transformations and deletes the original active file.  Step 3 should be
-skipped, because MATCH FILES creates its own case sink and writes to it in step
-7.  TEMPORARY is not allowed.
-
-MODIFY VARS:
-
-REPEATING DATA:
-
-SORT CASES:
-
-UPDATE: same as ADD FILES.
-
-VARSTOCASES: ???
-----------------------------------------------------------------------
-N OF CASES
-
-  * Before TEMPORARY, limits number of cases sent to the sink.
-
-  * After TEMPORARY, limits number of cases sent to the procedure.
-
-  * Without TEMPORARY, those are the same cases, so it limits both.
-
-SAMPLE
-
-  * Sample is just a transformation.  It has no special properties.
-
-FILTER
-
-  * Always selects cases sent to the procedure.
-
-  * No effect on cases sent to sink.
-
-  * Before TEMPORARY, selection is permanent.  After TEMPORARY,
-    selection stops after a procedure.
-
-SPLIT FILE
-
-  * Ignored by AGGREGATE.  Used when procedures write matrices.
-
-  * Always applies to the procedure.
-
-  * Before TEMPORARY, splitting is permanent.  After TEMPORARY,
-    splitting stops after a procedure.
-
-TEMPORARY
-
-  * TEMPORARY has no effect on AGGREGATE when output goes to the active file.
-
-  * SORT CASES, ADD FILES, RENAME VARIABLES, CASESTOVARS, VARSTOCASES,
-    COMPUTE with a lag function cannot be used after TEMPORARY.
-
-  * Cannot be used in DO IF...END IF or LOOP...END LOOP.
-
-  * FLIP ignores TEMPORARY.  All transformations become permanent.
-
-  * MATCH FILES and UPDATE cannot be used after TEMPORARY if active
-    file is an input source.
-
-  * RENAME VARIABLES is invalid after TEMPORARY.
-
-  * WEIGHT, SPLIT FILE, N OF CASES, FILTER apply only to
-    the next procedure when used after TEMPORARY.
-
-WEIGHT
-
-  * Always applies to the procedure.
-
-  * Before TEMPORARY, weighting is permanent.  After TEMPORARY,
-    weighting stops after a procedure.
