in thread Invalid argument

Liverpole -- I know I have a newline in my arguments, but I also have them being chomped in the subroutine. :-\
That's why i'm so confused.

    Because handlefix(); sends nothing to @_ in your sub.

    Take a look at perlsub, @_ is local

    grep
    XP matters not. Look at me. Judge me by my XP, do you?

    Whoops -- didn't read that far :-/

    It's because you're not passing @_.

    You could fix this with:

    handlefix(@_);
    but it's really better practice to chomp the variables on input, and assign them to actual variable names, leaving @_ to its better purpose of the default argument list.

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