+# Notes:
+#
+#  1) An empty Prompt field means there will be no prompt displayed
+#
+#  2) An empty Default Response field means that, if the user hits enter,
+#     the response is blank
+#
+#  3) An empty Legal Answers field mean the routine will accept *any* input

+#  4) It's up to you to make sure the Default Response is a legit answer.
