FORTRAN 77 is ''not'' a recursive language, in the specific sense that it does not support recursive algorithms. Local variables, in standard-conforming programs, were all treated by compilers more or less as what C programmers would call "static". |
FORTRAN 77 is ''not'' a recursive language, in the specific sense that it does not support recursive algorithms. Local variables, in standard-conforming programs, were all treated by compilers more or less as what C programmers would call "static". Subprogram parameters were all passed by reference, rather than by value as in C. |
