The "my $file " should be INSIDE the subroutine, not outside,
change the line above to
my $file = $_[0] || die ("No file specified\n");
or
my $file = $_[0] or die ("No file specified\n");
> open(FILE, "$file") || die("File could not be opened - $file\n");
No NEVER enclose variables in doublequotes by themselves. If
you need to insert the contents of a variable inside some text, the
you have to, but
"$variable"
is nonsense. (Yes, it seems to do the right thing. Now.)

The & in front of subroutine calls is deprecated (should not be
used).

Use full path. The current working directory is most probably NOT
what you might think it is.

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
