    ) As Variant

vLine: The string in which characters are to be translated. Function returns Null if vLine is Null or cannot be fixed up to a String (Behavior #1).

vFromToChars: The string containing pairs of characters that each describe how to translate one character into another. For example, a vFromToChars of "sXiY" tells this function to translate all "s" characters into "X" and to translate all "i" characters into "Y" Function returns Null if vFromToChars is Null or cannot be fixed up to a String (Behavior #2).

vCompare: Specifies the type of comparison used to determine if characters match (Behavior #3). vCompare defaults to Binary comparisons if it is missing or Null or cannot be fixed up to a number (Behavior #4).

Function uses the TranslateString function to actually perform the translation.
