  Hi,

I have tried running this script without any success unfortunately.  I have
updated the version of ns that I am running to the 2.1b3 version and the error
message that I get is that it cannot find/open the out.tcl file.

Could you explain to me how the nams now work without having to create a
separate nam script file?

Thanks for any help that you can offer,
