You can set $! ... but not to a specific error.
Try
foreach (0..30) {
$! = $_;
print "$!\n";
}
and
$! = "Hello world";
print "$!\n";
As you can see you can assign the error numbers, but not the
messages, those are fixed.
You need to use another variable to hold the error message.
You may also want to die("with the message") and wrap the code in an
eval{} block.
See
perldoc -f eval
