Описание

ArrayConstant represents array constant. Array can be one or multi dimensional. The dimension of an array may be specified by a type specification statement DIMENSION.

The value of the individual array elements of the array A may be initialized to the values 1, 2, 3, …, 10.

The assignment of the values of one array to another is allowed provided that both arrays in question have the same physical dimension.

An array may be allocatable, i.e., it may be assigned memory storage during execution.

Types

Only accepts integers, floating points as values of array indexes.

Examples

integer :: m(4)
m = [ 1, 0, 0, 2 ]
