 Did you see this link
<https://developer.mozilla.org/en-US/docs/WebAssembly/Reference>? Lots of
examples from there.

I promised a example of Hello World using my IL, and how to process and run it, in half a page. This is it for Windows :
------------------------------------
Paste the indented code into a file hello.pcl:
    addlib    "msvcrt"
    extproc    puts
    proc main:::
        setcall  i32 /1
        load     u64       "Hello World!"
        setarg   u64 /1
        callf    i32 /1    &puts
        unload   i32
        load     i32       0
        stop
        retproc
    endproc
Download the pc.exe file here: https://github.com/sal55/langs/blob/master/pc.exe, which is a 65KB file (UPX-compressed from 180KB). (Advice to navigate AV not included here.)
At a command prompt with both files present, type:
    pc -r hello
This will convert it to x64 code and run it. Use 'pc' by itself to see the 6 other processing options.
------------------------------------
So 20 non-blank lines. It would be nice if an equally simple example existed for WASM/WAT, or if people who suggested that choice could post a link to such an example /that/ works on Windows.
