Standards and the Operating System
Figure 3-1, Standards Supported and Enhanced by NonStop Products, on page 3-2,

The NonStop operating system, using the Open System Services (OSS) environment,
shown in the lowest level of Figure 3-1 is the base for application development.
Standards and the Operating System
The NonStop system environment has evolved its interfaces and functionality to allow
