I recently ran into an issue when moving from one build server to another - paths were different and it turns out there was a "hidden" hard coded path in the files that I wasn't aware of at first. 

The .gen file specified a hard coded $PBRPath and the contents of the .pbr specified a hard coded path to the location of a .pbl. 

I fixed all the hard coded paths and am building, but in doing so I have become quite confused about why we have this .pbr in the first place. The contents of the .pbr were simply: 

E:\BRMD\Build\BBR\libraries\driver.pbl(d_scheds_to_run)

From what I gather, this type of thing is necessary if a datawindow is not in a pbl. However, as best I can tell (which pretty much means just looking in the .pbl in the PowerBuilder IDE), d_scheds_to_run is there inside of driver.pbl.

Therefore, it looked to me like this .pbr file was probably not necessary. But when I removed the line in the .gen file that specified the .pbr location, the application stopped working as expected. In the code where it attempted to run Retrieve on a d_scheds_to_run object it returned a -1. So I guess this .pbr really is necessary but for the life of me I don't know why. 

Any advice would be great.

Hi Troy;

  PBR's are an absolute necessity when DWO's are dynamically assigned to either a DataStore or DW Control. If you app specifically assigns a DWO in the associated painter, then the DWO is included in the App. However, that is still not the absolute case.

  FWIW: I always use DLLs / PBD's for all my App Libraries on a compilation. That way there is A) No dependency on a PBR and B) you will always get all your DW objects (including Windows, User Objects, etc that are also dynamically assigned at runtime).. HTH

Regards .. Chris
