Is String Sorted Function
Sort Orders Class

Public Function IsStringSorted( _
      ByVal vString As Variant _
    , Optional ByVal vCompare As Variant _
    ) As Variant

Return True if the characters in a string are in ascending sorted order when examined from left to right.

Examples: 
    IsStringSorted("AaBbCc", vbTextCompare) = True
    IsStringSorted("AaBbCc", vbBinaryCompare) = False
    IsStringSorted("ABCabc", vbBinaryCompare) = True
    IsStringSorted("ABCabc", vbTextCompare) = False
    IsStringSorted("ABCabc") = IsStringSortedBinary("ABCabc")

vString: String whose characters are examined from left-to-right to determine if they are in ascending order. Function returns Null if vString is Null or cannot be fixed up to a String.

Empty strings and one character long strings are considered sorted.

vCompare: specifies the type of string comparison used to determine if characters match. vCompare defaults to Binary comparisons if it is missing or Null or cannot be fixed up to a number, which is the same as calling the IsStringSortedBinary function.
