FDL$ - File Definition Language

Overview

VX/FDL$ provides a call-compatible implementation of OpenVMS File Definition Language (FDL$) APIs for x86 and ARM Linux. It enables OpenVMS applications to define, generate, and manage file structures while maintaining compatibility with existing workflows.

Key Features

• Fully compatible with OpenVMS FDL$ APIs.

• Supports file structure definition, parsing, and management.

• Allows seamless migration of OpenVMS applications relying on FDL$ routines.

• Integrates with VX/RT to provide full OpenVMS file definition capabilities on x86 and ARM Linux.

• Maintains OpenVMS file structure semantics to ensure consistent behavior on Linux.
