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.
