1. A system for recording data characters on a form in a written representation, permitting use of the form as a business document, and in a punched code representation, permitting use of the form as a data processing system input device, said system comprising: first means for generating written representations of data characters on the form in any locations desired for making the form usable as a business document, said means comprising a typewriter having a plurality of character keys, each character key corresponding uniquely with a data character, each character having sensing means for sensing actuation of the character key; second means for generating first coded representations of the data characters which are defined by the generation of said written representations of data characters by said first means, said means comprising encoding means responsive to the sensing means for generating the first coded representation of the data character associated with an actuated character key; memory means coupled to the second means for storing the first coded representations of the data characters; card punch means coupled to the memory means for receipt therefrom of the first coded representations of the data characters for punching second coded representations of the data characters in the form in locations making the form usable as an input device for a data processing system; and control means for said memory means capable of alternatively assuming a first state in which said memory means is enabled to store the first coded representations of the data characters and a second state in which said memory means is enabled to apply the stored first coded representations of the data characters to said card punch means.
