Use of multiple inputs (from documentation) not working for me

[Shantanu Unknown]

I am trying to use multiple inputs.

The command on the help page 

http://www.gnu.org/software/parallel/man.html#example__use_multiple_inputs_in_one_command

parallel -a <(seq 6) -a <(seq 6 -1 1) echo 

is not working for me

It gives the error message

Missing name for redirect.

am using GNU parallel 20101115

on a centos 64 bit machine and tcsh

But I am get same error in bash shell

Any ideas?

Thanks
