NQC is a language/compiler which works with the standard LEGO firmware(s). I
don't anticipate that ever changing.
But here's a glimpse of something new for the Spybot target that might be
interesting to NQC users. Would 256 (or 128, if you want to protect your Spybot
game data) byte-sized storage locations be useful? Because these are byte-size
locations, there may currently be some problems with the tranformations that
certain operators use to calculate their result (such as >>).
#define a @(0x140000 + 0x80)
#define b @(0x140000 + 0x81)
task main()
{
a = 5;
b = 3;
a = a + 1;
a = a << 1;
a >>= 2;
a <<= 1;
a = a % 2;
a %= 2;
a = a + b;
a += b;
a %= b;
a *= 3;
a &= b;
a |= 3;
a ||= b;
b = -1;
a +-= b;
a ^= 0x80;
}
And I still think pointers are cool. I'm currently working on getting them to
work with inline function calls. But a lot of stuff works already.
int i = 30;
task main()
{
int x = 3;
int* y = &x;
// *&x = 4; // not supported
MyFred(y); // not emitted correctly
*y = 4;
int z = *y;
z = 4;
MyFred(&z); // not emitted correctly
//047 setv var[32], 33
//052 setv var[32], 4
// z = (*y)++; // not supported
// z = ++(*y); // not supported
int a[5];
a[2] = 2;
z = x*y;
z = x**y;
z = x & *y;
z = x&y;
y = &a[2];
y = &a;
}
void MyFred(int *x)
{
*x = 4;
// x = &i;
}
