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
Arrays are very well supported with memory allocation and set of intrinsics, better passing to procedures etc.
  • This is key capability for HPF
Derived Types allow general object structure (without inheritance) in F90
  • Pointers
  • This area NOT well supported by HPF Compilers as of Summer 1996
Modules replace COMMON INCLUDE etc.
Procedures (functions,subroutines) allow better interfaces, recursion, optional parameters etc.
Better Syntax with free form, more loop control etc.
