Specifications

Portable and Interoperable Application Support
2.1 Application Portability and Interoperability
The following software specifications, supported by OpenVMS, contribute
significantly to the creation of portable applications:
• Languages that conform to the American National Standards Institute (ANSI)
and the International Organization for Standardization (ISO) standards
• OSF/Motif graphical user interface
• Structured Query Language (SQL)
2.2 OpenVMS Support of Standards
OpenVMS supports a broad spectrum of national and international standards,
draft standards, and specifications. Some of the most significant standards that
OpenVMS VAX and OpenVMS AXP support are shown in Table 2–1. For a
comprehensive list of such standards, see the OpenVMS Software Overview. For
a comprehensive list of the standards that each Digital product supports, see its
software product description (SPD).
