Abstract

The schematically illustrated storage reading arrangement serves to modify decimal data on a digit level. Previous arrangements of this kind which modified the data in accordance with the format necessary for internal processing in a data processing system had the disadvantage that they shifted data only on a byte level and that data manipulation (e.g., data conversion from zoned to packed) was performed later in the arithmetic and logical unit.
