Release 10.1A: OpenEdge Development:
Progress 4GL Handbook

> ## Record Buffers and Record Scope

> This chapter continues the discussion on how to construct complex Progress 4GL procedures. It describes in detail the following concepts that were touched on in previous chapters:

> - What record buffers are and how they manage data for you.

> - More about how to use some of the string manipulation functions in Progress to manage lists of items for you.

> You’ll integrate these concepts with your GUI application to show the results of the calculations in your window for Customers and Orders. You’ll also go back to your test window from Chapter 2, "Using Basic 4GL Constructs," and define another user interface event for it to bring the data back to the window.

> This chapter includes the following sections:

> - Record buffers

> - Record scope

> - Adding procedures to the test window
