OLE (Object Linking and Embedding) is a Microsoft Windows standard for communications between applications. BlueZone can be linked to Windows applications like Microsoft Word and Microsoft Excel that support OLE.
In addition, BlueZone Host Automation Object can be used as a language-independent programmatic interface to BlueZone.
Using OLE, it is possible to use link Word to BlueZone in support of a "mail merge" application where the names and addresses are stored on a Mainframe and the text of the form letters are stored and formatted in Word. You could link Word to BlueZone and "pull" the names and addresses into Word from the Mainframe via the OLE interface.
