Nice work. I have a hard time wrapping my head around this. Can you just write
plain HTML to STDOUT using writeln and that's enough?
Write(ln) is a special call in Pascal.
In pas2js the handler for writeln is pluggable, and there is a unit that
installs a hook. The hook creates DIV's from the output, with special CSS.
The writeln() in WebAssembly works with imported file descriptor output
calls from the hosting environment.
What the pas2js environment does is catch the stdout file descriptor
and convert the strings to writeln() statements, which are then caught
by the hook and displayed.
Michael.
