in thread World Builder: the recovery and archeology of old programs.

kyle, I think that looping through the array you should not take the first match, but also verify that it is the only match. This to enforce the "minimal unique" requirement: if there are two options beginning with "kn" then "kn" is not a valid input but perhaps "kno" is.

Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."

    If you want to be sure you have only one match, do it this way... 

    my @picks = grep { ... } @menu;
if ( 1 < scalar @picks ) {
    die "Too many options match your input, '$input'\n";
}
$picked = $picks[0];
