end of character variable

end of character variable

end of character variable

(OP)
Hello,
with the following code, when NRuns becomes large enough e.g. 1000 the program stops at 495th iteration giving the following error:

'The end of the character variable in an internal file I/O statement was detected.'

Does anybody know what that means and if i can perform the iterations?

Thanx for reading.

CODE

  
program LOOP

implicit none
CHARACTER(LEN=50) :: string
INTEGER(kind=8)   :: NRuns,i,k,l

do i=1,NRuns
   .
   .
   .
  ! read from SCREEN.OUT
  OPEN(UNIT=80,FILE='SCREEN.OUT')

  ! read line 25 as string of characters
  READ(UNIT=80,'(25(/),50(A))')string
  l = LEN(string)
  k = INDEX(string,'=')

  ! read value after '='
  READ(string(k+1:l),*)value
  CLOSE(UNIT=80)

enddo

end program

do i=1,NRuns

  ! read from SCREEN.OUT
  OPEN(UNIT=80,FILE='SCREEN.OUT')


  ! read 24 lines

  do j = 1,24
  read(80,'(a)')string
  end do

  ! read line 25 as string of characters
  READ(80,'(A)')string

  l = LEN(string)

    if (l.gt.0) then
      k = INDEX(string,'=')

        if (k.gt.0.and.k.lt.l) then
  ! read value after '='
          READ(string(k+1:l),*,iostat=ierr)value

            if (ierr.ne.0) then
              write(6,*)'error reading line:-'
              write(6,'(a)')string
            end if

        end if

    end if

  CLOSE(UNIT=80)

end do

end program

Thanx that worked!

RE: end of character variable

You could also use end= instead of err=

RE: end of character variable

"err="  isn't in the code !

"end=" would be useful in reading the file as with

read(80,'(a)',end=999)string

but not for an internal read where "iostat=ierr" is used.


 

RE: end of character variable

Sorry, my mistake.

RE: end of character variable

xwb, no problem!
