A poor man's realization of recursive structured Fortran
Masataka Sassa · ACM SIGPLAN Notices · 1981
A simple method for converting Recursive Structured Fortran programs into Fortran programs is presented. By using a simple assembly-coded routine and getting slightly beyond standard Fortran such as using ENTRY statements, the method realizes recursive procedures and functions with "call by reference" parameters, which were not possible in previous methods. It imposes only few restrictions on users. Relevant implementation problems and solutions are discussed. By utilizing a macro processor, the converter was easily made. It deals with recursion simultaneously with "structuring" of Fortran.
