Abstract
Abstract Data previously entered in storage is corrected or changed independent of the location in storage addressed at the time the operator desires or determines that a change is to be made to such previously entered data. Storage devices are coupled to store the address of such location presently addressed and the address of the location where the data is to be corrected or changed. In addition to means for changing such data, further means are provided to enable entry of data into a predetermined number of locations following that location where the data is first corrected or changed after which yet further means enables the last-mentioned location to be automatically addressed. The operator is then enabled to operate the system to for example verify the just entered data or may return to the operation of entering data from the original location addressed at the time the operator decided to make a change in the data.
