Please forgive me - I need help! I'm a little rusty and I'm wondering if there's a better way of achieving the result I'm after.

I need to extract a string from a line within file. I will then use this string as a variable within my procedure.

The line always starts with the string "frz = ", and the value I need to extract comes after this.

Here's what I've got so far: 

open (CONFIG_FILE, "$config_file") || die

while (<CONFIG_FILE>) {
  if (($foo) = /^frz\s+=\s+(\w+)\;/) {
    $bar = $foo;
  }
}
print "$bar\n";
close (CONFIG_FILE) || die

So, I end up with $bar as the variable I can use.

My question is "Do I need $foo as an intermediate variable?" Is there a more 'elegant way of extracting the information I want?
