Pointing to array at an offset?

| How do I have one array pointer, from an empty array, point to the middle of another existing array? e.g. something like Local MyArray:Float[10] Local DummyArray:Float[] Varptr(DummyArray)[0]=Varptr(MyArray[5]) Obviously that's not right, but you get the idea. ???? I want to be able to point a temporary array pointer to the middle of a large existing array so that I can then read from the temp array as if offset 0 is in the middle of the original array, so that offsets indexes are simplified, without copying the array or creating a new one. |

if it doesnt have to be Float[]SuperStrict Framework brl.basic Local MyArray:Float[10] MyArray[0]=10 MyArray[1]=11 MyArray[2]=12 MyArray[3]=13 MyArray[4]=14 Local DummyArray:Float Ptr DummyArray=Varptr(MyArray[2]) Print DummyArray[0] Print DummyArray[1] |

| Hey, excellent, thanks! I was having to do array[offset+index] in a loop and didn't want to have to keep adding the offset all the time when it doesn't change. |
