IBM 1401 Programming for Card Systems: Preliminary Specifications


This bulletin describes five IBM 1401
utility programs, five frequently used
subroutines and four program error-
detection aid routine s for use in program
testing. 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.
