Abstract: A programming aid device for aiding in the interpretation of collimated fields of data in a computer printout. The device includes an inscribed data record which is in a format which corresponds to the collimated fields of the computer printout. When the device is positioned in association with a single row of the computer printout and properly aligned, the data record identifies the data fields of the computer printout. Eyecatcher data is provided in the data record to match up with identical eyecatcher data in the selected row of the computer printout to aid in the alignment of the data record with the selected row of the computer printout. The device also includes an information section for interpreting data in the selected row of the computer printout in accordance with designator data associated with predetermined fields of the data record.
