An Application Arbortext PE written in VBScript is a VBScript subroutine which takes no parameters. The Arbortext PE Request Manager processes requests for VBScript applications by passing requests whose f parameters have the value vbscript to the Request Function com.arbortext.e3.FunctionVbscript. The request function allocates an Sous-processus Arbortext PE and passes the request to the Application Arbortext PE Context (described in The Sous-processus Arbortext PE Application Context). The Application Arbortext PE Context allocates request and response objects, as for a Java application, and stores references to them in global variables. Then it calls the VBScript function indicated by the request's function parameter. The function must have been defined in a .vbs file in a custom\init directory or in a .vbs file in custom\scripts which is loaded from custom\init.

VBScript Application Arbortext PEs are specifically for Windows systems. The VBScript Application Arbortext PE is called without any parameters. It obtains request and sets response information by invoking methods in the packages PEAppRequest and PEAppResponse, which access the request and response objects allocated by the Application Arbortext PE Context.

The return value of the VBScript Application Arbortext PE function is ignored. Whether it succeeds or produces an error response, everything to be returned to the client must be stored in the response object.

Unlike a Java Application Arbortext PE, a VBScript application has no initialization or termination components.
