    FirstNonMatchingCharacter(1, "4455CBA", "45ABCDEF") = ""

vStartPos: The position of the character in string vLine where the search is to begin. vStartPos defaults to 1 (one) if it is Null or cannot be fixed up to a number.

vLine: The string which is to be searched from left-to-right for characters that do not appear in string vFindChars. Function returns Null if vLine is Null or cannot be fixed up to a String.

vFindChars: String containing characters whose appearance within string vLine is to be ignored. Function returns Null if vFindChars is Null or cannot be fixed up to a String.

vCompare: Specifies the type of 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.

Function returns an empty string if all of the characters within vLine also appear within vFindChars.
