The Blue Book methods crTab and crTab: were omitted because they can be easily composed using cr and tab.

 

The message flush is included to support polymorphic programming using CLDT streams and CFS file streams. Sending flush to a CLDT stream has no effect.

 

The message print: is not in the Blue Book, but is provided to assist in using cascading messages when writing the description of objects.

 

All these messages except next:put: and print: are part of the ANSI standard.
