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 There are three typical cases:
2 Subroutine requires data to use a particular mapping determined by subroutine
  • Arguments must be remapped
3 Subroutine can use any mapping so actual argument should be passed and used with current mapping

5 Any remappings must be undone on return from subroutine
