OpenVMS RTL Library (LIB$) Manual

This manual provides detailed usage and reference information for the library routines supplied in the LIB$ and CVT$ facilities of the OpenVMS Run-Time Library (RTL). It is intended for system and application programmers who need to call these routines from high-level languages.

The document is structured into three parts:

• Overview: Provides a summary of the LIB$ and CVT$ Run-Time Library facilities and guidelines for using the LIB$ facility on VAX and Alpha platforms.
• LIB$ Reference Section: Contains detailed, alphabetical descriptions of each routine in the LIB$ library, including their purpose, format, arguments, and return values.
• CVT$ Reference Section: Provides documentation for routines in the CVT$ Run-Time Library facility, specifically focusing on floating-point data type conversions.

The manual includes numerous examples of how to use these routines in various programming languages (such as Fortran, Pascal, BASIC, C, and COBOL) and provides detailed tables describing data formats, error/condition codes, and macro usage for state-driven parsing (LIB$TPARSE/LIB$TABLE_PARSE).
