+ Prohibit LAG following TEMPORARY. This both matches SPSS behavior
+ and fixes a bug: we saved the cases for LAG before TEMPORARY but
+ allowed access to variables created afterward anyhow (which could

+
+ * generate.pl: Parse "perm_only" flag on operations.
+
+ * operations.def: Add "perm_only" flag to LAG operations.
+
+ * parse.c: Disallow OPF_PERM_ONLY operations after TEMPORARY.
+
+ * parse.inc.pl: Output OPF_PERM_ONLY flag for "perm_only"
+ operations.
+
+ * private.h: Add OPF_PERM_ONLY flag.
