in reply to A simple,

  1. Concatenating the list with " " causes it to evaluate in a scalar context. In a scalar context, reverse returns the reverse of the concatenation of all elements of the list. The space will be concatenated to the end of that.

  2. The following code should do what you want to do:
    #!/usr/bin/perl - w use strict; my @list = qw (first second third fourth fifth sixth + seventh eigth ninth tenth); print join ' ', reverse (@list);
    And here's another way:
    #!/usr/bin/perl - w use strict; my @list = qw (first second third fourth fifth sixth + seventh eigth ninth tenth); my @reverse = reverse (@list); print "@reverse";
