[String->IsWhiteSpace] checks whether a specified character within the string is white space. Accepts an optional integer parameter for the position of the character in the string to check, defaulting to the first character if omitted. The method returns True if the character is white space or False otherwise.
'String Object'->iswhitespace 'String Object'->iswhitespace(Integer)
