Corner case. What about starting a multi-line comment, running it to the end of the source file and not closing it? ;)

Great job, HD.

When you've implemented functions, you should add Allegro-interfacing functionality, then we could write entire games in it.

Cool! One of the few courses that actually had my attention in my second year at uni was Scheme as a functional programming language. But admittedly, this book had something to do with that. Believe it or not, depending on the project, I like to use a Lisp dialect as the scripting language.

Have you considered having special code for handling regular mathematical expressions? I know, it's great that math functions are nothing more than any other function, but still, the code readability increases 10-fold, and it isn't that much more work (believe me, I rewrote that like 5 times from scratch for all my scripting language projects :P and didn't break a sweat) :)

I'm always interested in seeing how other people implemented theirs. [smile]

f(int &a)
{
    a=a*(-2+6)/((3*-a)-1);
}

string g(int z)
{
    if(z==10) return "hello";
    else if(z==9)
        {
        int b=10;
        while(b>0)
            {
            out "looping - ",b,"\n"; b=b-1;
            }
        }

    return "goodbye";
}

proc 0 // this is one of potentially many entry points
{
    out g(10),"\n",g(9),"\n";
}

proc 1
{
    int x=10; f(x); out x,"\n";
}

namespace ic
{
	enum code { end,call,ret,svc,
             		        setrx,setax,
				movra,movar,movrs,
				getrg,putrg,
				get,put,
				mpush,mpop,
				push,popn,poke,peek,
				add,sub,mul,div,neg,
				eq,neq,lt,lteq,gt,gteq,
				land,lor,lnot,
				jmp,jz,
				outn,outs,outb };
}

@Easily: How long did it take you whip all of that up? As I recall, it seemed nearly overnight that you had a fully fledged assembly-like language + VM ready to go for Udo.

Additionally, how do you manage communication/access between the script and the actual C++ program? Your language is already far more feature-complete than mine. [smile]

bool Service(int Code,int *Regs,CImp &Imp)
{
    switch(Code)
        {
        /* ... */

        case 4: Regs[0]=PC->GetX(); Regs[1]=PC->GetY(); break;

        /* ... */
        }

    return true;
}

getplayerxy(int &x,int &y)
{
    service(4); x=register(0); y=register(1);
}

Aye, definitely opt for the Scheme course. I found it very unwieldy initially, but the way that the language is so compact (well, at least the foundations are :P) and clearly defined makes it such a nice model to work with, and has helped me understand programming languages in general a lot better. Best of luck!
