[MPIWG Fortran] Type of MPI_Status

[Rolf Rabenseifner]

Jeff,

based on Bill's explanations
I understand that all is the same:

KIND(0) =  KIND(1) = KIND(237834) 
= KIND(any default INTEGER number)

= KIND(any default INTEGER variable) = KIND(ICVDhjk)
= KIND(INTEger)

provided that there is no "IMPLICIT NONE"and therefore,
the with I beginning variables ICVDhjk and INTEger
are automatically of type default INTEGER

Remark: You should never use KIND(INTEGER) because it may 
cause a name conflict if the MPI applications declares an
own variable with name INTEGER.

Best regards
Rolf
