Position inside StringVariable where substitution will start. If PositionStart is negative, the starting position is assumed to be PositionStart characters from the end of the string.

If ByLen is omitted, all of replacement string is used. If ByLen is negative, it is interpreted as: LEN(StringVariable)-ABS(ByLen).
