The PPG Library
Overview
PSC offers a library of several sample PPG program source files which include examples of file manipulation, templates, and nodes. Several working programs are included, although many of them are only examples and do not provide any functional value. You can download these files from the Technical Support area of PSC’s website at www.pscnet.com. This section briefly describes each of these files.
