    Abstract: A system for use in a keypunch application. Keyed data is recorded onto a magnetic card. To prevent interruption of the keying rhythm during movement of the read-record head from track to track and during card feed, a two-sectioned memory is employed, which through selection of a single address and gated logic allows data to be transferred from one section to the other section without need of buffering or other types of temporary storage or delay. The two-sectioned single address memory is also utilized during verify and duplication operations with, in the case of the latter, the data from a first record being entered from the keyboard into the first section of memory and being transferred to the second section for transfer to the magnetic card. During duplication into a second record from the keyboard, data is transferred back into the first section from the second section through utilization of the single address technique.

    Abstract: The accounting system is operator-oriented and includes arithmetic and stored program facilities. The system features entry of program instructions through a ''''program by example'''' routine in which the operator enters control (program) information concurrently with the entry of data during conventional typing routines. That is, as the problem is worked, the steps in the operation are stored in program memory. The system is then able to execute the program in a repetitive manner accepting additional keyed-in data, performing calculations, and printing necessary output documents. The system is particularly useful with accounting forms having information arranged in columns. Additional features involve manipulation of column registers, one associated with each column, the branching techniques, decimal point control, determination of true percentages (Percent Equal), use of the Alpha Emit function and the provision of various input and output devices including a magnetic card apparatus.
