It's not entirely clear from your code what you intended t
Well the thing will work but its useless because you
are not reading from the file here. You are applying
the while loop on a scalar instead of providing it
with the file desc that it needs for the "logical
processing".

## The way you have defined file_read
## you should pass the handle of the file
## by opening it
You can pass in a variable it would be something like this:
$lofile = " somefile";
file_read($lofile) ;
sub file_read($)
{
my ($file) = @_;
while (<$file>)
blah..blah..
}
