![](images/i.jpg) *In general, performing plane-at-a-time operations can make almost any Mode X operation, at the worst, nearly as fast as the same operation in mode 13H (although this sort of Mode X programming is admittedly fairly complex). In this pursuit, it can help to organize data structures with Mode X in mind. For example, icons could be prearranged in system memory with the pixels organized into four plane-oriented sets (or, again, in four sets per scan line to avoid a fading-in effect) to facilitate copying to the screen a plane at a time with **REP MOVS***
