[Expectperl-discuss] How to make an expect string optional

[avonnieda <ad...@vo...>]

   Hi Folks,

  I have one line in a program I'm automating that will prompt sometimes,
not always. How can I make an expect line "optional". In other words, ignore
this block if you don't see the string before the timeot is reached. Here's
the block I want to make optional.

   $expect->expect($timeout,"Do you want to preserve the port number");
   $expect->send("n\n");

   Thanks very much for any insight.

      -Adam
