A summary and comparison of language attributes is given in Table 1. Of the six languages surveyed, PL/I and FORTRAN are best suited to composite design. COBOL is also well suited, provided that modules are represented as subprograms, and not as performed paragraphs. Composite design can be used with APL, although the APL problems discussed often cause undesirable compromises to be made. Composite design does not lend itself well to the design of RPG and ALGOL program: both lack the concept of a module, and RPG lacks the concept of arguments and parameters.
