Abstract:

The Programming, Administration, and Execution PAX system is a mainframe-based timesharing system that provides the U.S. Army Corps of Engineers with a number of crucial budgeting, planning, and scheduling applications. Like any mainframe-based system, PAX is expensive to operate and maintain, but it may be possible to reduce costs by converting PAX applications to Ada, the computer language mandated by Congress and the Department of Defense. While offering a number of potential advantages, conversion to Ada would also pose some significant problems. This report examines the advantages and disadvantages of converting the PAX system to Ada. Issues discussed include PAX programming and implementation practices, conversion options, availability of compatible compilers and software tools, training, and costs. The authors recommend against converting PAX to Ada at this time due to cost and technical considerations. Recommendations also are offered for how to make the transition most effectively should policymakers decide to proceed with conversion to Ada.
