ISO/IEC 99999-1 - Programming languages - PROTO
PROTO - the fake SC22 web demonstration language - consists of a
small number of features, in addition to the normal
programming language stuff:
-  Exception handling
-  Facilities to simplify interoperability with the C language, in order to enable PROTO programs to access, and interact with, operating system features more easily 
-  Enhancements to derived data types to allow allocatable components and parameterized types
-  Features to allow object oriented programs to be written in PROTO
-  Facilities to enable PROTO programs to take advantage of internationalization features provided through the operating system
