New features of WSH 5.6 (script Host) _vbs

In this latest version of the Windows Script Host (version 5.6), several features are described:

• Improved parameter handling-it is simpler to process and record command-line arguments. Simplifies the integration of scripts with other command-line scripts and makes it easier to create scripts that can provide help information to users. Please refer to the following table for information about the WSH language features to familiarize yourself with this new feature.

  Determines whether the derived script procedure is currently running.	Status Property (wshscriptexec)

  Accesses the StdOut output stream of the derived script procedure.	StdOut Property (wshscriptexec)
  Accesses the STDERR output stream of the derived script procedure.	StdErr Property (wshscriptexec)
  Terminates the derived script process.	Terminate Method (Wshscriptexec)
  Accesses a named command-line script parameter.	Wshnamed objects
  Determines whether a particular key value exists in the Wshnamed object.	Exists method

• can run scripts remotely-You can download scripts to several remote computer systems and run them at the same time. When you run a remote script, you can view its processes. After the script runs, you can make sure it is running correctly or that you can determine the cause of the premature termination. There is a new Send object, the Controller object, that is used to create the remote WSH object. In addition, there is a new object that represents the running instance of the script, the Remote WSH object.

• When you start a new procedure, you can treat them as objects -determine the state of the derivation process and access their standard I/O flow.
