Hi:
How are you executing your stored process -- what client application? Enterprise Guide? The SAS Add-in for Microsoft Office? The Information Delivery Portal? The SAS Stored Process Web Application? Web Report Studio? For example, if you are using the Stored Process Web Application to execute a stored process, via URL (as in an HTML form action), you can code the appropriate target= attribute.
Without more information, it is hard to answer your question.
