Supports porting of Unix system based software products into BS2000

Current Version: A45

POSIX (Portable Open System Interface for Unix) is the set of standardized interfaces available under Unix systems according to POSIX / XPG4.2.
POSIX in BS2000 enables the easy run of programs of the Unix world after porting them to BS2000 systems. This means that a large number of widely used Unix applications, especially in the field of Internet technologies, can be used on a BS2000 system.
The operating system BS2000 features standardized interfaces conforming to POSIX / XPG4.2. The POSIX-BC function complex in version A45 is delivered as part of OSD/BC V11.0 and V10.0 from general release of OSD/BC V11.0.
Open, POSIX-based applications benefit from the business-critical computing properties of BS2000. These properties include high availability, great scalability, mass throughput of data and highly cost-effective operation in data centers.
POSIX also serves as the technical platform for implementing services that enable interoperability and connectivity between BS2000 and the open systems world; the entire BS2000 system can in fact be expanded into a full internet Server.
