And that, assuming what you are looking for is not on the last non terminated line (which would be missed because -f is not there, although note that you can read that last non terminated line inside the {{mIRC|on sockclose}} event), should be fine. In fact, in this specific example and in general, it will work, because you are making sure %a is a full line or nothing. Well that's why it works in most situation, you are checking that %a is a specific text, which would fail if no byte were read into %a because a terminated line couldn't be found. However, if you are in a situation where you must check that %a is $null (usually because it read an empty $crlf line), you must check {{mIRC|$sockbr}} to know if you read bytes at all, a good example of this usage is shown below, which discard the headers of HTTP (check for an empty value after /Sockread %a reads an empty $crlf line):
