The internal CPU memoryfor this data is 7680 bits long. For Series 90-70 systems, the programming software subdivides thisrange using %G, %GA, %GB, %GC, %GD, and %GE prefixes—allowing each of these prefixes to beused with bit offsets in the range 1–1280. For PACSystems, these ranges are converted to %G.
