====Indexing====

Almost all assembly languages have a method of loading from a memory address offset by some sort of variable amount. That offset is the index into the array. Depending on the size of each element that index is multiplied by the number of bytes each element takes up. What constitutes an "element," "row," or "column" of the array is entirely decided by the programmer. Arrays in assembly are always zero-indexed.
