Obsolete Language Elements
The language elements described in this subnode are obsolete and are still available only for reasons of compatibility with older releases. You may still come across these statements in older programs but you should not use them in new programs.
Most of the obsolete language elements listed here are forbidden in the syntax of classes or in Unicode programs. As a result, they can now only be used outside of classes or in non-Unicode programs. There are replacement constructions for all obsolete language elements, which improve the efficiency and readability of programs.
