in reply to what's this loo code?

I don't see the point, but breaking it down:

  • Read from file: <>
  • Read in array context; i.e., get all lines from file: ()=<>
  • Assign those read lines to $=. That's the page length for formatted output: $==()
Basically it's saying, make the format page length the size of the number of lines in file. But just printing that doesn't really do a whole lot unless I'm missing something ...

    Assign those read lines to $=

    No. Assign the length of the right hand side expression in the assignment.
