In “Workfile Basics,” we described the basics of workfiles; how to create and work with a workfile, as well as the basics of using multi-page workfiles. In this chapter, we describe advanced workfile types and tools for working with workfiles.

First, we describe the fundamentals of structured workfiles. You will need to understand the concepts underlying structured workfiles to work with irregular dated data, data involving cross-section identifiers, or panel structures.

Next, we outline various workfile level tools for managing your data. Among other things, we discuss the basics of resizing a workfile, saving a workfile to foreign formats, subsetting a workfile, and rearranging the format of the data in your workfile.
