Running and examining examples

Once you have located an example that performs some processing
you want to learn about, you can run it to examine how it works
and look at the code (and copy it if you want to).

Running an example

To run the highlighted example, double-click it or click Run!.
You can get Help on how to use the example and what it does by clicking
the Help button on the example’s main window.

Examining the code

To see all the objects used in an example, click the Related
Objects tab on the right pane and click the plus signs to expand
items:

Double-click the icon for a script or function to examine
it.

Using examples in the development environment

Running the Code Examples application and looking at the code
for an example gives you a lot of information, but if you open objects
in the examples in the development environment, you can examine
them in more depth.

For example, you can open any object in a painter, examine
the inheritance hierarchy in the Browser, and step through an example
in the Debugger. You can even copy objects to your own application
in the Library painter or copy code fragments to the Script view.

The libraries in the Code Examples application are organized
by object type. For example, pbexamd1.pbl and pbexamd2.pbl contain
DataWindow objects. This makes it easy to find the objects that
are referenced as examples later in this book. If you expand the
sample libraries in the List view in the Library painter, the comments
tell you what each object is used for.
