ArrayConstant¶

Array constant.

Declaration¶

Syntax¶

ArrayConstant(expr* args, ttype type, arraystorage storage_format)

Arguments¶

Argument Name	Argument Description
`args`	expression arguments
`type`	table entry type
`storage_format`	array storage format

Return values¶

The return value is the expression that the Array Constant represents.

Description¶

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 ]
