Array Sections

We can select sections of an array using the following subscript-triplet

The subscripts of the array section start at , are incremented by and stop at or before . The selected subscript values are similar to the values of the DO-loop variable generated by the statement

The bounds and the stride must be integer-valued expessions; if missing, they are assumed to take implicit values as follows:

• missing : = subscript's lower bound, as declared.
• missing : = subscript's upper bound, as declared.
• missing : .

For example, let

be the array . Note that the subscript's lower bound is , and upper bound is . Then the following sections can be selected

A(1:3)
A(1:3:2)
A(1:4:2)
A(3:1)	zero sized section
A(3:1:-1)
A(:)	whole array
A(4:)
A(:2)
A(::4)
A(2:2)
A(2)	scalar element

Note that a section of the array is an array itself.

As a second example, consider

REAL, DIMENSION(4,4) :: B
