The above programs were de- veloped for use on 1401 systems using card input and card or printed output. Each program is easily adapted to per- form its function in conjunction with the user f s programs. Flexibility of the programs provides for using either 100 or 132 positions of printing, where appli- cable, as well as providing for adapting the programs for use on 1401 systems equipped with 1400, 2000, or 4000 posi- tions of core storage.
