- Common User Access (CUA) defines conventions for GUI
look and feel.
- Common Programming Interface (CPI) provides languages,
tools, and APIs that give applications greater portability
and more consistent user interfaces across multiple
platforms.
- Common Communication Support (CCS) supports existing
communications standards, such as LU 6.2.

demonstrations of SAA concepts and make it easy for users
to migrate between systems.
