Hi james734,

Your problem, more likely than not, is that there's a newline character at the end of $file;

Try adding the line: 

$file = <STDIN>;
chomp $file;

Another piece of advice is to use $! when printing errors that result from system calls: 

open(IN, $file) or die "The file $file is not present ($!)\n";

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
