IOSTAT in READ

[Mike896]

Hi

I have a file like this:

0.5715 0.2378-1416.9485

It should have at least one space between the second and third data. But the number(3rd one) is too large.

I'd like to detect this kind of file from several files, if this error happens.

I used

read(....,IOSTAT=ios) a,b,c

I print ios values for every file including the above example.

I find every ios is 0, i.e. success reading.

How to detect the above file as a failed one?

If I neglect "IOSTAT=ios" in READ, then I get "list-directed i/o syntax error...."

Thanks

Mike

Mike,
The "usual" way to do this is to read the data into a character string [read (lu,'(a)') string] and parsethe stringyourself, that way you have full control over error handling etc.
