I'd like perl to replace $variables in a file. The vars are simply listed as $a, $a+50, $b etc in a file, which I read. I use the following: 
$a=1;
$b=2;

....
    while ($line = <INFILE>)    {
        chomp($line);   # contains $a, $b
        print "$line\n"; #prints "$a" "$b"

However, perl ignores all the $variables and print them explicitly. How do I make perl specify the variable value when prining $line?

Thx,
