PROGRAM Example
    IMPLICIT NONE
    INTEGER :: rows, columns, errcheck
    INTEGER, ALLOCATABLE :: array(:,:)
    
    rows = 5
    columns = 10
    ALLOCATE (array(rows,columns), STAT=errcheck) ! STAT is optional and is used for error checking
    array(3, 3) = 999
    WRITE(*,*) array(3, 3)
    DEALLOCATE (array, STAT=errcheck)
