Terminating reading of .txt file

Terminating reading of .txt file

(OP)
Hey everyone!

I'm new to fortran and would like to get some help from you pros out there! It would really help a bunch.

Basically, my problem is that I have a .txt file, of unknown number of rows, which contains data in the following format:

**start**
equipment(a), value1, value2, value3, value4
equipment(b), value1, value2, value3, value4
equipment(c), value1, value2, value3, value4
.
.
.
End
**end**

I have no problems reading the data I need using the following code in a DO loop:
READ (1,*) equipment, a, b, c, d

However, I get an error when I want to terminate reading the .txt file. I'm currently using this syntax to exit:
IF (equipment=="END") EXIT

Are there any ways to terminate upon reading the "END" line? Your help is much appreciated! Thank you :)

RE: Terminating reading of .txt file

for example something like this:

CODE

...
  integer :: stat
  ...
  ! open input file
  open(10,file='my_file.txt',status='old')

  do
    read(10,*,end=99, iostat=stat) my_val01, my_val02, ...
    if (stat .ne. 0) then
      write(*,*) 'Error reading data !'
      go to 99
    end if
    call process_my_data
  end do

  ! close file
  99 continue
  close (10)
...
