Foil 5 Important Features of Fortran90

From New CPS615HPF and Fortran90 Discussion Sept 17 96 Basic Simulation Track for Computational Science CPS615 -- Fall Semester 96. by Geoffrey C. Fox, Tom Haupt
1 Arrays are very well supported with memory allocation and set of intrinsics, better passing to procedures etc.
  • This is key capability for HPF
2 Derived Types allow general object structure (without inheritance) in F90
  • Pointers
  • This area NOT well supported by HPF Compilers as of Summer 1996
3 Modules replace COMMON INCLUDE etc.
4 Procedures (functions,subroutines) allow better interfaces, recursion, optional parameters etc.
5 Better Syntax with free form, more loop control etc.
