Abstract : The report describes a Higher Order Language (HOL) Cost Effectiveness Study whose major objectives are to: Compare HOL effectiveness with assembler language effectiveness in terms of cost, manpower and time requirements; Study the technical feasibility of various compiler design and implementation techniques; Provide the criteria to be evaluated when determining whether a HOL should be used for particular avionic applications. The objectives of the study were realized through the accumulation of industry-wide data on HOL related studies and developments. This data was then combined with extensive information obtained within IBM from experience in avionic programming projects, language research activities, and language development programs. An objective measurement of HOL versus assembler cost effectiveness was obtained through a statistical analysis of model programming activities. The criteria to be evaluated when determining whether a HOL should be used for particular avionic applications is presented in a series of related questions which must be answered for each specific application. These questions take the form of a decision flow diagram which becomes the tool which is used to answer the basic HOL or NOT question. The entire report is tied together through a final notes and observation section which links various questions in the decision flow diagram to specific sections within the report. (Author)
