File length

[cjkogan111]

Hello,
Lets say that I have a file -

5 4 3
9 2 4
2 5 3
2 1 1

And I am reading in variables a,b,c.

Does anyone know how I determine the # of lines in the file before I read it in?

Thanks!

I think you can't, you either start with that number and read that number, so...

4
5 4 3
9 2 4
2 5 3
2 1 1

or you read till end of file DO WHILE(.NOT.EOF(1)) etc
you count the lines and you read again after allocating

Any other suggestions are welcome, I don't know anything better

Regards,

Gerrit

I think you can do this using the inquire function, but I'd have to admit that I can't get it to work..
Something along the lines of:

inquire (unit=21, recl=n)

then n should be the file length. Except that this doesn't work, but I'm pretty sure it's something like that.
