hello, i'm trying this "proof of concept" script, to make sure i can modify the output of a ps for a given perl script, as stated on perlvar manpage. 
$ cat ps_info.pl
#!/usr/bin/perl
@a = ( "one", "two", "three", "four", "five" );
for (1..50)
{
    print $0 . "," .$a[$c%5]."\n";
    $0 = $a[$c%5];
    $c++;
    sleep 2;
}
exit;

this script outputs: 
$ ./ps_info.pl
./ps_info.pl,one
one,two
two,three
three,four
four,five
five,one
one,two
two,three
three,four
four,five
five,one
one,two
two,three

showing that the "$0" is being assigned different values, although, the "ps xww" does not show any difference, it sits there like this the whole time the script runs: 
 5578 pts/5    S      0:00 /usr/bin/perl ./ps_info.pl
