I am trying to auto generate my host file for a grid deployment.
The following works well if I actually put a number in the of the for

let b_final_oct=$first_grid_node_final_oct
let b_grid_size=$grid_size
b_pub_sub_net=$pub_sub_net

Thanks Michael. That's a winner. let... I guess that is from scripting
past of some sort. Thanks for the cheetahtemplate.org ref.
