The Generator of Body Data (GEBOD) program is an interactive computer program that produces the human and dummy body description data used by the Articulated Total Body (ATB) model. GEBOD computes the body seg¬ ments' geometric and mass properties, and the joints' locations and mechanical properties. These data may be computed for children, adult human males, adult human females, or anthropomorphic dummies. This report is a comprehensive manual that covers the applicable material from earlier reports and the most recent upgrades to the GEBOD program, including improved height calculations. The user's guide section of the report describes how to run the program and what options are available. A more detailed description of how the data is generated and on what studies the calculations are based is included in the program descrip¬ tion section. Also included are a brief history of GEBOD's development, a detailed description of GEBOD program subroutines, and example output files.
