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.
