But even with DBIT_VAR, "i" will get incremented twice! The first time when DBIT_VAR is assigned with "i" and a second time in the following code...

Making the Bit16_Get function as a stock function could solve this.

//Edit: I've tried my luck with nibble coding.^^

pawn Код:

#define Nibbles:%0<%1> \
    %0[((%1) + 8) >>> 3]

stock Nibble_Get (arr [], slot)
{
    new shamt = (slot & 7) * 4; // (slot % 8) * 4
    return ((arr [slot >>> 3] & (0x0F << (shamt))) >>> shamt);
}

stock Nibble_Set (arr [], slot, val)
{
    new
        shamt = (slot & 7) * 4, // (slot % 8) * 4
        s = slot >>> 3;
    arr [s] &= ~(0x0F << shamt); // Set target "cell" to 0.
    //arr [s] |= (val << shamt); // Using this, you have to make sure that val < 16 or other cells may get changed.
    arr [s] |= ((val & 0x0F) << shamt); // This looks more save to me.
}

I'm absolutely not sure if this works. I didn't test it.
