+ * Revision 1.14  1996-05-09 07:28:49  quinn
+ * Work towards phrases and multiple registers
+ *
+ * Revision 1.13  1996/05/01  13:44:05  adam
+ * Added seek function to the recExtractCtrl and recRetrieveCtrl control
+ * structures. Added end-of-file indicator function and start offset to
+ * recExtractCtrl.
+ *
+ * Revision 1.12  1996/01/17  15:01:25  adam
  * Prototype changed for reader functions in extract/retrieve. File
  *  is identified by 'void *' instead of 'int'.
