Abstract : The report addresses two problems. The first is to provide an evaluation of the relative merits of the programming languages PL/I and JOVIAL, as constituted by the Version 4 and J-3 compilers, with particular emphasis on ADS Command and Control applications. It is concluded that while both languages are quite adequate, PL/I is much the better and a more powerful language than JOVIAL. The second problem is concerned with ADS data management within an IBM OS/360 operating system environment. The proposed J-4 COMPOOL capability is felt to be quite good and general. It is possible, in a straight forward manner, to provide an equivalent capability both in PL/I and an extension of J-3 within OS. (Author)
