Yes, and it rather looks as though you don't. asm.js has strictly 
numeric types, so you can't write a conventional "Hello, World!" in it. 
If you want to do that, then you have to write it in a suitable 
high-level language: I suggested Javascript, but I can see how that 
could be confusing so let's just accept /anything/ here.

Now if something like that can't, ultimately, be run from a shell or a 
makefile it's going to be problematic for an FPC port. It's going to be 
particularly problematic for the various tests that are run 
automatically to test the compiler's correctness: it's all very well 
saying that in the target environment FPC -> asm.js is used strictly to 
run apps in the context of Firefox but that's hardly going to be 
convenient for working through a large corpus of test cases.

Yes. I'll say no more lest I let irritation get the better of diplomacy.
