Coba bandingkan output program dalam Nusa dan dalam C untuk kasus program ini (saya menggunakan compiler Nusa YANG TERBARU YANG ADA DI yahoogroups, kecuali mungkin Anda pakai versi terbaru yang belum dirilis, maka tidak fair menghakimi orang lain tidak teliti).


yohanes@pinguin:~/comp$ cat ab.nusa
program ab;

integer a();

integer test(integer a)
{
       writeline(3+a);
               return 3+a;
}

integer a()
{
       return 4;
}

void main()
{
       writeline(test(3));
}

yohanes@pinguin:~/comp$ ./Compile ab.nusa
