This handbook is for the student with little or no previous experience with computer utilization for data processing. Sample problems to be run on the computer are included. It gives: (1) an overview of the sequence of steps from obtaining data to receiving computer output, (2) a guide to common computer packages, (3) an illustration of the use of systems cards, (4) discussion and exercises on writing variable format cards, (5) coding considerations, (6) the rationale and illustrations of the use of transgeneration cards, and (7) an appendix of related descriptive materials. The book is designed to ease the transition form a nonuser to user of standard library (canned) computer programs--programs that satisfy most of the researcher's needs. The book is designed for the user who has access to a computer facility that has the BMD and/or other standard library packages. One section of this book is not entirely generalizable to other computer installations since system cards are indiosyncratic. Those employed illustrate the CDC 6400 system at the University of Colorado. (Author/SE)
