It will be known to the compiler after parsing; it might not be known to 
you!

(I hope, that when posted, it doesn't wrap.)

This is meant to be incorporated into some program source code. To avoid 
annoying you, let's pretend that's C, then I'd need to book-end it like 
this:

    char data[] = {
       <block of text from above>
    };

Now, you're saying I ought to know what goes inside '[]'. Well, not 
really. Perhaps the program generating that data could print that value. 
Or I could count columns and rows and work it out. But I don't really 
want to have to hardcode that value inside [].

Maybe I will regenerate that data (perhaps it will be included from some 
file that I don't even look at) then I'd have to update the number.

It just shouldn't be necessary.

The largest set of data I've included this way I think was 100M numbers. 
That was testing embedding. But I have included actual binary data (eg. 
images and executables) like this too.

It was about 45 years ago, and I never managed to try it out for real 
until A68G came about.

Those decades of real-life experience (whatever your opinions about 
that), opened my eyes more to its practicial deficiencies. It's clearly 
a language that belongs more in academia.


(If curious about what those bytes mean, it is the machine code of a 
function to solve the LIBFFI problem for Win64 ABI, that normally 
requires a complex external library to be built from source.

Although not meant to be used from C, I tried it just now, and it works.

This is something not possible in standard C, yet C gives me the ability 
to incorporate that binary code, and pass it control. This is what more 
practical languages allow you to do.)
