BAS$ - BASIC Runtime Support

BAS$ - BASIC Runtime Support

Overview

VX/BAS$ provides a call-compatible implementation of the OpenVMS BASIC Runtime (BAS$) API for x86 & ARM Linux . It ensures seamless execution of OpenVMS BASIC applications by preserving existing runtime behaviors and functionality.

Key Features

• Fully compatible with OpenVMS BAS$ APIs.

• Supports essential BASIC runtime functions such as string conversion, editing, execution control, and system interactions.

• Allows seamless migration of OpenVMS applications using BAS$ runtime routines.

• Integrates with VX/RT for enhanced portability on Linux

• Preserves existing development processes without requiring major code modifications.

VX/RT BAS$ Callable Routines

BAS$ API Function
BAS$CVT_S_DConvert string to double
BAS$CVT_S_LConvert string to long integer
BAS$CVT_S_WConvert string to word
BAS$EDITPerform string editing
BAS$SLEEPSuspends execution for a specified duration
BAS$SYSTEMExecute system command

Why Use VX/BAS$?

• Enables direct porting of OpenVMS applications that depend on BAS$.

• Provides full compatibility with OpenVMS BASIC runtime services.

• Supports essential runtime operations, ensuring OpenVMS BASIC applications run without modification.

• Seamlessly integrates into the VX/RT ecosystem for complete OpenVMS compatibility on Linux.

VX/BAS$ ensures that VMS applications requiring BAS$ services can be migrated without major modifications, preserving productivity and minimizing development costs.
