If you have a lock on the file, you can then release it.

@a = <$fh>;

There are reasons to load the file into an array. That's one of them, and I listed four others. But that's not the code the OP posted, and that's not the code I proclaimed should be avoided. You did not contradict me, or do you think I've already contradicted myself four times?
