What users have to say:
BBC BASIC for Windows is an advanced implementation of BBC BASIC for PCs running Microsoft Windows™ (Windows 95, 98, Me, 2000, XP, Vista, Windows 7 or Windows 8), providing the programmer with a familiar language but with a modern interface. It combines the simplicity of BASIC with the sophistication of a structured language, allowing you to write utilities and games, use sound and graphics, perform calculations and create complete Windows™ applications. In short, using BBC BASIC you will be able to make your PC do what you want it to!
The Graphical User Interface includes a BASIC program editor with syntax colouring, live indentation, search & replace and many other features (see the screenshot below). Built-in diagnostic aids such as run-time trace, listing of variables and single-step execution make debugging even the most complex programs straightforward.
Up to 256 Megabytes of memory is provided for the user's program, data and stack (subject to sufficient RAM being available). Unlike some older versions of BASIC, you won't suffer the frustration of running out of memory! Line numbers are optional.
BBC BASIC for Windows uniquely incorporates an assembler which generates 32-bit code and accepts all 80486 instructions and some Pentium-specific instructions (except special-register and privileged instructions), including floating-point and Multi Media Extensions. You can access the Windows™ Application Program Interface both from BASIC and from assembler code, allowing an experienced programmer to produce sophisticated applications.
The full version allows you to create a compact (typically less than 100K) stand-alone executable (.EXE) file from your BASIC program, which will run without BBC BASIC having to be installed and without the need for any special DLLs. You can distribute such executables freely without any royalty for BBC BASIC being due.
BBC BASIC for Windows is largely compatible with Version 5 of BBC BASIC resident in the Acorn Archimedes and Iyonix computers. It also retains a high degree of compatibility with the BBC Microcomputer, including emulation of the SOUND and ENVELOPE statements, and the MODE 7 (teletext) screen mode.
However this is by no means a language stuck in the past: it is fully integrated with Windows™ and has many new and advanced features including data structures, PRIVATE variables, long strings, event interrupts, an address of operator, byte variables, a line continuation character, indirect procedure and function calls and improved numeric accuracy.
