WRUNET IEXP,SEXP1,SEXP2,SEXP3,SEXP4,SEXP5

 Function
  Write information to the USERNET file for a specific node.

 Syntax
  WRUNET node,stat,name,city,oper,br

   node  - An integer expression with the node to update.
   stat  - A string expression with the new node status.
   name  - A string expression with the new node user name.
   city  - A string expression with the new node city.
   oper  - A string expression with the new node operation text.
   br    - A string expression with the new node broadcast text.

 Remarks
  To facilitate internode communications, a file named USERNET.XXX is
  maintained with an entry for each node on the system.  This file is used
  by the BROADCAST command of PCBoard and to prevent multiple
  simultaneous logins, among other things.  This statement may be used to
  change information for the current node (for example, to update
  operation text during PPE execution) or other nodes (for example, to
  broadcast a message).
