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

Function returns 0 (zero) if vFindChars is an empty string.

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