How do you keep track of line numbers with a longer perl script? What I

What about just jumping to line 230?
- In EMACS M-x goto-line 230. Besides, the current line number is always
indicated in the status line.
- I vi I believe it's :230 but my vi is _very_ rusty.
- Heck, even Notepad has a Goto Line functionality.
What editor are you using that it doesn't know about line numbers?

Gosh, juergen, I was unaware that notepad had that functionality.
While I am a "windows guy," I've never really developed any continuing
education with it because I haven't ever been in a place on usenet where
The Topic can be bothered for a practical user concern.
Line 230 is the sysopen line here:
sub check_lock {
$time = $_[0];
for ($i = 1;$i <= $time; $i++) {
if (-e "$data_dir$lock_file") {
sleep 1;
}
else {
sysopen(FH, $path, O_WRONLY|O_EXCL|O_CREAT) or die $!;
print LOCK "0";
close(LOCK);
last;
}
}
}
There's no great surprise here, as I've got no file for it to open, so I
think I'm at the level where I can't pursue this further.
Does this address the file lock issue adequately?
