I keep having this prevert thought of writing a UCSD P-Code to WebAssembly converter, making Pascal cool again, riding the WASM hype wave.

You probably already know, but FPC (the Free Pascal Compiler) supports two WASM compilation targets: WASI and embedded - https://wiki.freepascal.org/WebAssembly

RemObjects' Elements compiler (which supports Object Pascal, C#, Java, Go, and Swift) can also output WASM - https://docs.elementscompiler.com/Platforms/WebAssembly/

boring! UCSD p-code is a stack based virtual machine. WASM is a stack-based virtual machine. Converting one to the other is an interesting project.

I was aware, but not how far they have come already, thanks for heads up.
