Example of absolute array: var EGAVGAScreen : Array[0..41360] of Byte absolute $A000:0000; Et voila : bounds-checked memory mapped hardware access. (note: the very well known "Crt" unit uses a memory mapped video buffer like this. So if you programmed a turbo pascal program, chances were good it was using this trick for screen output. Advantage : the speed is unbeatable)
