-* Modification History:
-*
-* Date Name Description
-* 02/19/97 aliu Converted from java.
-* 03/20/97 helena Finished first cut of implementation and got rid
-* of nextDouble/previousDouble and replaced with
-* boolean array.
-* 4/10/97 aliu Clean up. Modified to work on AIX.
-* 06/04/97 helena Fixed applyPattern(), toPattern() and not to include
-* wchar.h.
-* 07/09/97 helena Made ParsePosition into a class.
-* 08/06/97 nos removed overloaded constructor, fixed 'format(array)'
-* 07/22/98 stephen JDK 1.2 Sync - removed UBool array (doubleFlags)
-* 02/22/99 stephen Removed character literals for EBCDIC safety
