A PowerBuilder library (PBL) is a binary file. It stores objects you define in the PowerBuilder painters in two forms: source and compiled. The source for an object is text. The compiled form is binary and is not readable by humans.
The Library painter lets the PowerBuilder developer view and maintain the contents of a PBL. The painter lists the objects in a PBL with their properties, such as modification date and comments.
In the Library painter, the PowerBuilder developer can delete, move, compile, export, and import objects, and can use source control systems and create PowerBuilder dynamic libraries and DLLs.
From the Library painter, you can open objects in their own painters and view and modify the objects graphically.
