InfoMaker uses libraries and special files.
PBL files are the libraries you work with in InfoMaker. In the Library painter, you manage the objects in these libraries. In other painters, you create and access objects stored in PBLs.
When you open the Library painter the first time When you open the Library painter, the Library painter has your computer as the root. You can set the Library painter to display objects in the current library, tutor_im.pbl. This is the default InfoMaker library that contains sample objects based on the EAS Demo DB.
Many examples shown in this book are in tutor_im.pbl for your convenience. You can open the objects, look at their design, and use them.
Two libraries are installed in the InfoMaker 12.5 directory when you install InfoMaker: imstyletradition125.pbl and imstylecontemp125.pbl. These libraries are used as templates to create new objects in InfoMaker and should not be opened and edited. Do not set one of these libraries as your current library. If you do, its name will not display in the Library pane in the Open, Run, and Save dialog boxes. You must open another existing library or create a new one to work in InfoMaker.
PSR files contain reports. Each PSR file contains a report definition (source and object) as well as the data contained in the report when the PSR file was created.
