Can I use HLLAPI applications with BlueZone?
BlueZone supports several different versions of HLLAPI, 32- and 16-bit, WHLLAPI, EHLLAPI and Extended EHLLAPI (EEHLLAPI).

It’s compatible with any 32-bit PC application that has a Visual Basic or C HLLAPI (High Level Language Application Programming Interface) link to TN3270, TN5250, VT100, VT220, SCO ANSI or Wyse 60 terminal emulation. In most cases, the application will work without any modification.

What is the BlueZone Host Automation Object?
BlueZone offers the Host Automation Object (HAO) which is a COM object that can be loaded by any COM compliant scripting language or programming language. It currently supports the proprietary BlueZone interface, the NetManage Chameleon Automation Object, the Attachmate Object interface and the WRQ Object and Method interface.

The HAO is used by many BlueZone customers in a wide variety of applications including:

• Microsoft to embed the collection of host-based data in an Excel or Word document
• VBScript and JScript scripts to automate data input called in Web pages that launch BlueZone Web-to-Host, then to navigate to specific host screens using data obtained from the Web page
• Single sign-on applications to take the user ID and password from a local store and log the user into a TSO session
