BROADCAST IEXP1,IEXP2,SEXP

 Function
  Broadcast a single line message SEXP to nodes from IEXP1 to IEXP2
  inclusive.

 Syntax
  BROADCAST lonode,hinode,message

     lonode   - An integer expression containing the low node number to
                which the message should be broadcast.
     hinode   - An integer expression containing the high node number to
                which the message should be broadcast.
     message  - A string expression containing the message text which
                should be broadcast to the specified nodes.

 Remarks
  This PPL statement functions the same as the PCBoard BROADCAST command,
  which is normally reserved for SysOp security level.  This statement
  allows you to programatically broadcast a message to a range of nodes
  without giving users the ability to manually broadcast at any time they
  choose.

 Examples
  ' Broadcast a message to a specific node
  BROADCAST 5,5,"This broadcast from "+STRING(PCBNODE())
  ' Broadcast to a range of nodes
  BROADCAST 4,8,"Stand-by for log off in 10 seconds"
  ' Broadcast to all nodes
  BROADCAST 1,65535,"Hello all!"
