For Calculator HubNet, this primitive acts in exactly the same manner as hubnet-broadcast. (We plan to change this in a future version of NetLogo.)
For Computer HubNet, it acts as follows:
For a string, this sends value from NetLogo to the tag tag-name on the client that has string for its user name.
For a list-of-strings, this sends value from NetLogo to the tag tag-name on all the clients that have a user name that is in the list-of-strings.
Sending a message to a non-existent client, using hubnet-send, generates a hubnet-exit-message.
See the HubNet Authoring Guide for details.
