+//  CARDUTIL.C 
+//
+//  Utility File for all common card routines.
+//
+//  History:
+//
+//      02-20-93 KJB/SG First, Placed SG's CardGetNumber function here.
+//      03-25-93  JAP   Fixed up typedef and prototype inconsistencies
+//      05-12-93  JAP   Added version control information.
+//                          This file should be updated changing the version numbers
+//                          on EACH significant change to ANY low-level driver. 
+//                          The cause of upping a version should be placed in this
+//                          files history. (currently Version 1.0)
+//      05-12-93  KJB   Moved code from cardtxxx.c to here.
+//      05-12-93  KJB   Fixed bugs in CardGetVersion.
+//      05-15-93  KJB   Fixed warnings in CardGetNumber.
