Mikhail,
I do use this teqnique whenever I have to, because sometimes its necessary. However, it makes for fragile and confusing code. Its much better to use the specific error trap routine to do this:
READ #1, using form$(1) : mat f$, mat f nokey TestNoKeyError
...
...
TestNoKeyError: ! Have your code for this error here.
Or, actually, here's an even better way:
READ #1, using form$(1) : mat f$, mat f nokey Ignore
if File(1)<>0 then
... handle your nokey error here
...
...
end if
See, using the FILE function returns the last error recieved with that file. You don't have to reset it because it resets automatically each time the file is read. The dirty work is done for you.

Wouldn't FILE(1)<> 0 be true in other cases as well, and not only if there is a NOKEY?
I think FILE returns
-1File not opened. 0Operation performed successfully. 10End of file occurred during input. 11End of file occurred during output. 20Transmission error during input. 21Transmission error during output.
And NONE of these values is used specifically for NOKEY, at least not according to the documentation I'm looking at.

Yes, File(1) will be 10 if there is a nokey. But I find that I generally want to do the same thing (ie, stop reading) no matter what file(1) is. If file(1) is 0, I read, if not, i don't read.
If you want to make sure you are testing for NOKEY, then still, don't use ERR. Its messy and unreliable.
Instead, use the NOKEY error condition.
READ #1, using form$(1) : mat f$, mat f NOKEY HandleNokeyError
Then, later you have a line somewhere called HandleNoKeyError
HandleNoKeyError: ! Handle the error here
...
...
continue ! or retry or whatever you want to do
Does this help?
