1401 Data Analysis and Reduction System
(1l401-CA-04Xt Version 2
Programmer's and Operator's Manual
The IBM 1401 Data Analysis and Reduction System is a
powerful series 6f programs to generate tabular and statistical
reports from existing card or magnetic tape files. Three types
of programs, modified by control cards to suit individual
requirements, operate under the control of a monitor program.
The data preparation programs accept punched cards or
magnetic tape in a variety of formats, and add, delete, and/or'
change the format and content of each record or user-selected
records from the data file. Records may be selectively
extracted for information retrieval purposes.
The report programs produce, as specified in control cards,
m.atrix-type, frequency tabulation, listed, punched and
statistical reports. The matrix reports, consisting of
horizontal columns and vertical rows, present crossfooted
di.stributions expressed in percentages, counts, or sum.maries
as required. The frequency tabulation report contains the
frequency of occurrence of the values in a specified field of
every data record. The quantitative statistical report contains
parameters such as the mean, variance, and standard
deviation, along with a matrix-type presentation of frequency,
count, and percentage for each defined group.
The utility programs provide the ability to list records,
control program operating sequence, prepare and modify the
system tape, and perform various other functions to facilitate
using the system.
The programs can be used in almost any industry to provide
a concise analysis of subjects such as inventory activity,
traffic characteristics, sales analysis, communications
systems, engineering studies, medical reports, payroll
analysis, and personnel studies.
