Inquiry Intrinsic Function (Generic): Returns the total number of elements in an array, or the extent of an array along a specified dimension.
Syntax
Results:
The result is a scalar of type integer. If kind is present, the kind parameter of the result is that specified by kind; otherwise, the kind parameter of the result is that of default integer. If the processor cannot represent the result value in the kind of the result, the result is undefined.
If dim is present, the result is the extent of dimension dim in array; otherwise, the result is the total number of elements in array.
The setting of compiler options that specify integer size can affect the result of this function.

Examples
If B is declared as B(2:4, -3:1), then SIZE (B, DIM=2) has the value 5 and SIZE (B) has the value 15.
The following shows another example:
REAL(8) array (3:10, -1:3)
INTEGER i
i = SIZE(array, DIM = 2) ! returns 5
i = SIZE(array) ! returns 40
