My latest assignment from my book (not a school assignmetn, I don't know if you have rules for that here. I am teaching myself perl.) asks me to create a program that can read another program line by line and reverse each line. I don't necessarily want the answer yet but I am getting a particularly unhelpful error that I can't debug. How do I fix it? The error is "syntax error at ./ioexperiment.plx line 7, near "foreach @line " Execution of ./ioexperiment.plx aborted due to compilation errors." The code is: 
#!/usr/bin/perl -w
use strict ;
my ($a, @line) ;
print "Please specify a file." ;
chomp ($a = <STDIN>) ;
open ($a) ;
foreach @line ($a) {
    print reverse(@line);
}
