An array declaration (or array declarator) declares the shape of an array. It takes the following form:

(a-spec)

a-spec

Is one of the following array specifications:

Explicit-shape
Assumed-shape
Assumed-size
Deferred-shape
Assumed-rank
Implied-shape

The array specification can be appended to the name of the array when the array is declared.

Examples

The following examples show array declarations:

SUBROUTINE SUB(N, C, D, Z)
  REAL, DIMENSION(N, 15) :: IARRY       ! An explicit-shape array
  REAL C(:), D(0:)                      ! An assumed-shape array
  REAL, POINTER :: B(:,:)               ! A deferred-shape array pointer
  REAL, ALLOCATABLE, DIMENSION(:) :: K  ! A deferred-shape allocatable array
  REAL :: Z(N,*)                        ! An assumed-size array
  INTEGER, PARAMETER :: R(*) = [1,2,3]  ! An implied-shape constant array
