1. Concurrent Object-Oriented LanguaGE. 2. CLIPS Object-Oriented LanguaGE? 3. A C++ class library developed at Texas Instruments. COOL contains a set of containers like Vectors, List, Hash_Table, etc. It uses a shallow hierarchy with no common base class. The functionality is close to Common Lisp data structures (like libg++). The template syntax is very close to Cfront3.x and g++2.x. Can build shared libraries on Suns. JCOOL' s main difference from COOL and GECOOL is that it uses real C++ templates instead of a similar syntax that is preprocessed by a special ' cpp' distributed with COOL and GECOOL. .
