带数组的 Fortran 子例程

Question

我在这个程序中的子程序有问题，它位于程序的末尾。我在子例程中得到一个数组划分错误，它说“不可分类的语句”。希望有人能帮忙！

PROGRAM subroutine1
IMPLICIT NONE

INTEGER:: err, ierr, counter, y ,i ,j 
!INTEGER, ALLOCATABLE:: gamenum(:)
CHARACTER(30):: fname
REAL, ALLOCATABLE:: AB(:), H(:), TB(:), BA (:), SP(:)

100 Format (A)
200 Format (I2)
300 Format (F9.3)

! 1.Open file

WRITE(*,100)"Please enter a filename:"
READ(*,*) fname

OPEN (UNIT=10, FILE=fname, STATUS="OLD", ACTION="READ", IOSTAT=err)
IF(err.NE.0) STOP "An error occured when opening the file."

! 2.Count Lines

READ(10,*)

counter=0
DO
    READ(10,*,IOSTAT=ierr)
    IF(ierr .NE. 0) EXIT
    counter=counter+1
END DO

!WRITE(*,200) counter

! 3. allocate array

ALLOCATE(AB(counter)) 
ALLOCATE(H(counter))
ALLOCATE(TB(counter)) 
ALLOCATE(BA (counter)) 
ALLOCATE(SP(counter))

! 4. read in data

REWIND(10)

READ(10,*)

DO i=1,counter
    READ(10,*) AB(i), H(i), TB(i)   
END DO

REWIND(10)

! 5. Call subroutine

    CALL arraycalc(counter,AB,H,TB,BA,SP)

! 6. Write out
WRITE(*,100)"Game    AB       H       TB       BA       SP" 

DO i=1,counter
    WRITE(*,200,ADVANCE="NO") i
    WRITE(*,'(5F9.3)') AB(i), H(i), TB(i), BA(i), SP(i)
END DO

END PROGRAM subroutine1

!HERE IS THE PART WHERE I'M HAVING TROUBLE  

SUBROUTINE arraycalc(counter,AB,H,TB,BA,SP)
IMPLICIT NONE

INTEGER, INTENT(IN)::counter
INTEGER::i
REAL,INTENT(INOUT)::AB,H,TB
REAL,INTENT(INOUT):: BA,SP

DO i=1,counter
    BA(i)=H(i)/AB(i)
END DO

DO i=1,counter
    SP(i)=TB(i)/AB(i)
END DO

END SUBROUTINE

Answer 1

在子程序内部，AB、H、TB、BA 和 SP 没有声明为数组，所以给出错误的语句确实没有意义。它们是标量，因此不能被索引。
