StrToBool will convert the string S to a boolean value. The string S can contain one of 'True', 'False' (case is ignored) or a numerical value. If it contains a numerical value, 0 is converted to False, all other values result in True. If the string S contains no valid boolean, then an EConvertError exception is raised.


On error, an EConvertError exception is raised.
