+* Modification History:
+*
+*   Date        Name        Description
+*   02/19/97    aliu        Converted from java.
+*   03/20/97    clhuang     Implemented with new APIs.
+*   03/31/97    aliu        Moved isLONG_MIN to DigitList, and fixed it.
+*   04/3/97     aliu        Rewrote parsing and formatting completely, and
+*                           cleaned up and debugged.  Actually works now.
+*                           Implemented NAN and INF handling, for both parsing
+*                           and formatting.  Extensive testing & debugging.
+*   04/10/97    aliu        Modified to compile on AIX.
+*   04/16/97    aliu        Rewrote to use DigitList, which has been resurrected.
+*                           Changed DigitCount to int per code review.
+*   07/09/97    helena      Made ParsePosition into a class.
+*   08/26/97    aliu        Extensive changes to applyPattern; completely
+*                           rewritten from the Java.
+*   09/09/97    aliu        Ported over support for exponential formats.
+*   07/20/98    stephen     JDK 1.2 sync up.
+*                             Various instances of '0' replaced with 'NULL'
+*                             Check for grouping size in subFormat()
+*                             Brought subParse() in line with Java 1.2
+*                             Added method appendAffix()
+*   08/24/1998  srl         Removed Mutex calls. This is not a thread safe class!
+*   02/22/99    stephen     Removed character literals for EBCDIC safety
+*   06/24/99    helena      Integrated Alan's NF enhancements and Java2 bug fixes
+*   06/28/99    stephen     Fixed bugs in toPattern().
+*   06/29/99    stephen     Fixed operator= to copy fFormatWidth, fPad,
+*                             fPadPosition

+ * PATTERN_MINUS, and kCurrencySign.  If kCurrencySign is doubled (kQuote +
+ * kCurrencySign + kCurrencySign), it is interpreted as an international
+ * currency sign. If CURRENCY_SIGN is tripled, it is interpreted as
+ * currency plural long names, such as "US Dollars".
+ * Any other character after a kQuote represents itself.
+ * kQuote must be followed by another character; kQuote may not occur by
+ * itself at the end of the pattern.
+ *
+ * This method is used in two distinct ways.  First, it is used to expand
+ * the stored affix patterns into actual affixes.  For this usage, doFormat
+ * must be false.  Second, it is used to expand the stored affix patterns
+ * given a specific number (doFormat == true), for those rare cases in
+ * which a currency format references a ChoiceFormat (e.g., en_IN display
+ * name for INR).  The number itself is taken from digitList.
+ *
+ * When used in the first way, this method has a side effect: It sets
+ * currencyChoice to a ChoiceFormat object, if the currency's display name
+ * in this locale is a ChoiceFormat pattern (very rare).  It only does this
+ * if currencyChoice is null to start with.
+ *
+ * @param pattern the non-null, fPossibly empty pattern
+ * @param affix string to receive the expanded equivalent of pattern.
+ * Previous contents are deleted.
+ * @param doFormat if false, then the pattern will be expanded, and if a
+ * currency symbol is encountered that expands to a ChoiceFormat, the
+ * currencyChoice member variable will be initialized if it is null.  If
+ * doFormat is true, then it is assumed that the currencyChoice has been
+ * created, and it will be used to format the value in digitList.
+ * @param pluralCount the plural count. It is only used for currency
+ *                    plural format. In which case, it is the plural
+ *                    count of the currency amount. For example,
+ *                    in en_US, it is the singular "one", or the plural
+ *                    "other". For all other cases, it is null, and
+ *                    is not being used.
