Preprocessor system 'EOS' for a variable-array-size program

As a part of the project TRITON a preprocessor (EOS preprocessor) has been developed. This preprocessor converts an EOS source program in which variables and arithmetic expressions are usable to define sizes of arrays into a usual fortran source program in which only constants are usable for the purpose. The EOS preprocessor forms a preprocessor system with an inverse preprocessor (the inverse EOS preprocessor) which converts a fortran source program into an EOS source program. As the alteration of sizes of arrays becomes extremely easy by using the EOS preprocessor, this system is very useful in development and use of large-scale computer codes. This report can be used as a user's manual of the EOS preprocessor system. (author)
