nl_tokens: When the compare method is called with two arguments x and y it returns a Number other than NaN that represents the result of a locale - sensitive String comparison of x with y . The result is intended to order String values in the sort order specified by the effective locale and collation options computed during construction of this Collator object and will be negative zero or positive depending on whether x comes before y in the sort order the Strings are equal under the sort order or x comes after y in the sort order respectively .
pl_tokens: <mask> compare ( collator , x , y ) { return % InternalCompare ( % GetImplFromInitializedIntlObject ( collator ) , TO_STRING ( x ) , TO_STRING ( y ) ) ; }
