The concept of managing data in FORTRAN programs is introduced and illustrated by following the evolution, through several stages of development, of a simplified program that has the essential features of larger nonlinear structural analysis programs. The relevant characteristics of FORTRAN are reviewed and the techniques of dynamic dimensioning are considered. A FORTRAN data manager is provided in both simple and production versions. Listings of all essential coding are included along with some tips on data management. The paper concludes that the problems of program portability and adaptability can be reduced considerably if FORTRAN data management functions are relegated to an appropriate set of data managing routines. The emphasis in the paper is on the management of main memory data but a brief description is given of a family of programs for managing secondary storage.
