2. Implemented and missing parts of the Chill language

The numbers in parentheses are Z.200(1988) section numbers.

• The FORBID keyword in a GRANT statement is currently ignored.

• A CASE action or expression allows only a single expression in a case selector list (5.3.2, 6.4).

• ROW modes are not implemented (3.6.3, 3.13.4).

• Due to the absence of ROW modes, DYNAMIC has no meaning in connection with access and text modes.

• Array and structure layout (PACK, POS, NOPACK, STEP keywords) is ignored (3.12.6).

• Bit-string slices are not implemented.

• The support for synchronization modes and concurrent execution is slightly non-standard.

• Exception handling is implemented, but exceptions are not generated in all of the required situations.

• Dynamic modes are not implemented (though string slices should work).

• Reach-bound initializations are not implemented (4.1.2).
