Data initialization

Compile-time data initialization can be carried out using type declaration statements and DATA statements. The format of the DATA statement is fully described in Chapter 10, where the initialization formats for each of the intrinsic type declarations are also specified.

In the following example, data is declared and then initialized, using DATA statements:

INTEGER i

LOGICAL test

CHARACTER(LEN=10):: string

REAL,DIMENSION(2,4) :: array

COMPLEX,DIMENSION(3) :: zz

DATA i,test,string/21,.TRUE.,'10 letters'/

DATA zz/3*(1.0,2.0)/ ! Using a repeat factor.

DATA ((array(i,j),i=1,2),j=1,4)/1.0,2*2.0,5*3.0/

! Using an implied DO loop.

! i = 21 test = .TRUE.

! string = '10 letters'

! All elements of zz = (1.0,2.0)

! The 8 elements of array are

! 1.0 2.0 3.0 3.0

! 2.0 3.0 3.0 3.0
