I have a follow up question! Will the following snippets always end with a newline or be 200 bytes long, if the end of the file isn't reached and there are no errors/signals?

{
   local $/ = "\n";
   $line = <FILE>;
}

{
   local $/ = \200;
   $record = <FILE>;
}
[download]

> cat > test.pl
$/ = \10;
$record = <STDIN>;
print("[", length($record), "]\n");

> perl test.pl
