Format charts are used to direct the manual entry of digital data into record cards such as sense-mark cards that are processed in an automatic data processor. The format charts have parallel indexing lines that define different combinations of the sense-mark data columns, as well as means for identifying the class of data to be entered in each of the combinations of columns. The charts are linked as a string of sequential charts, and a mechanism is provided for moving the format charts and positioning them one at a time with their indexing means adjacent to and in parallel relation to the columns of the sense-mark cards, so that the various combinations of columns are visually related to the format identifications of data classes and data may be manually entered in a sequence of the cards.
