GoKawiilFoxDev Studio revives FoxProclass programming with 64-bit engine
A new project called FoxDev Studio recreates the Visual FoxPro language on a fully 64-bit foundation, removing the 2GB table and memo-file limits that came from Visual FoxPro's 32-bit signed integer file handling. It uses a Rust-built compiler and bytecode interpreter compiled to WebAssembly, echoing FoxPro's original p-code compiler-and-runtime design, and shares the same editor and runtime code paths so type-checking matches execution behavior exactly.
GoKawiil's interpretation of the reporting above, not reported fact.
Because Microsoft stopped developing Visual FoxPro after version 9 in 2007, longtime users have been stuck with a 32-bit architecture that caps table sizes regardless of available hardware; this project suggests a path to keep FoxPro-style applications viable on modern systems. The move to WebAssembly could also mean such applications become portable across platforms without rewriting, though how compatible the new tool truly is with legacy Visual FoxPro codebases remains to be seen in practice.
- FoxDev Studio removes the 2GB table/memo limits inherent to Visual FoxPro's 32-bit file format.
- Tables grown beyond 2GB in FoxDev Studio can no longer be opened in the original Visual FoxPro, a one-way compatibility break.
- The system uses a Rust-based compiler and WebAssembly runtime, mirroring FoxPro's original compile-to-bytecode approach.
