+Loop index variables are by default reset to system-missing from one
+case to another, not left, unless a scratch variable is used as index.

+variable as the loop index.

 When @cmd{LOOP} or @cmd{END LOOP} is specified following @cmd{TEMPORARY}
 (@pxref{TEMPORARY}), the @cmd{LAG} function may not be used
 (@pxref{LAG}).
