+/* Case initializer.
+
+ The procedure code has to resize cases provided by the active
+ file data source, to provide room for any other variables that
+ should go in the case, fill in the values of "left" variables,
+ and initialize the values of other non-left variable to zero
+ or spaces. Then, when we're done with that case, we have to
+ save the values of "left" variables to copy into the next case
+ read from the active file.
+
+ The caseinit code helps with this. */
