[Name] OpenArgs [Data Type] Variant [Description] 
A string expression. This expression is used to set the form's OpenArgs property. This setting can then be used by code in a form module , such as the Open event procedure . The OpenArgs property can also be referred to in macros and expressions . For example, suppose that the form you open is a continuous-form list of clients. If you want the focus to move to a specific client record when the form opens, you can specify the client name with the openargs argument, and then use the FindRecord method to move the focus to the record for the client with the specified name.
