EViews work files and objects

EViews does not open a generic blank file, unlike Word, Excel, etc.

EViews documents are also called working files and need to be created instead of generic. These working files contain information such as your data.

EViews are object-oriented programs. All objects are related to this particular analysis, such as sequences, groups, equations, drawings, tables, and so on.

The working file is the owner of these objects.
