Modules are divided into the Categories listed in the top-left area of the VPE window:

The directory /usr/lpp/dx/samples/programs contains visual program examples that use these modules, along with a subdirectory .../SIMPLE of simpler examples. Use the "Open Program" item in the "File" menu of the VPE. When the file-selection dialog box is displayed type in either directory (adding /*.net ) to the directory name when you enter it in the Filter text field). For a description of a visual program, either highlight the program name in the Files list of the dialog box and click on the "Comments" pushbutton or select the "Application Comment" option of the "Help" pull-down menu (after the visual program is loaded).

The above directions assume that DX is installed on the machine you are using.
