in reply to Automatically running series of Perl programs

There are several ways including using backticks `` around each command. Most people probably prefer using the system command. You could also open each program on a file handle: 
open PROG "perl foo.pl param1 | " or die "...";

Then you can handle the io.

You could also simplify your three steps into one and write a shell script (did I really suggest that?): 

perl foo.perl param1 | perl bar.pl | perl tins.pl > result.txt

    Yeah, I think you really did suggest that. Furthermore, I'd suggest a shell script, too. I usually use Perl scripts rather than shell scripts even when a shell script would do quite well enough, but this really strikes me as something simple enough that using Perl is complete overkill and a waste of time, unless running the three other scripts in sequence is part of a larger algorithm somehow.
