In previous versions of 4D, when placing variables, expressions and other debugging items in the Expression area of the debug window, it was retained in subsequent debugging sessions (within the same 4D session).

Now in 4D v11 SQL, you must save this information using the "Save" toolbar button. If you place debug items in the Expressions window and do not save, the items will be gone when you finish that debug session and it will be required to add them again if you need for future debug sessions.

Using the "Save" button will save the debug information and it will persist for future sessions.
