                   1401 DATA PROCESSING SYSTEM BULLETIN



PROGRAMS FOR IBM 1401 CARD SYSTEMS: PRELIMINARY SPECIFICATIONS

This bulletin is a minor revision of, but does not supersede, the original edition, form J28-0209. The changes
are in the first paragraph of Clear Storage Routine (with respect to the card column mentioned) and in the first
and third paragraphs of Print Storage Program.


This bulletin describes five IBM 1401 utility programs, five frequently-used subroutines
and four program error-detection aid routines for use in program testing. The above
programs were developed for use on 1401 systems using card input and card or printed
output. Each program is easily adapted to perform its function in conjunction with the
user's programs. Flexibility of the programs provides for using either 100 or 132
positions of printing, where applicable, as well as providing for adapting the programs
for use on 1401 systems equipped with 1400, 2000 or 4000 positions of core storage.
