Hello, I'm trying to simulate a routing protocol that involves dividing the nodes into groups. I want to be able to specify the number of groups in a simulation in the Tcl script (pretty much like the number of nodes is specified), but if I define the number of groups, for instance, val(groupno) in the Tcl file, I don't know how to access and use that number in the routing protocol code. Any help would be appreciated. Thank you. Nancy Ibrahim
