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.
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

"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.
