I am happy to be more specific. First off, I understand it can be difficult to get started not knowing the first step so I can help with that. A couple of questions, have you worked with C# or PowerShell? Even Python would probably be ok. But let's get a baseline on tech. Are you a programmer or an analyst? Have you worked with xpath by any chance?
To help, take one of your egp files and just change the extension to zip and look at the contents.
I can even write the code for you since I have a small amount of free time. If you have an egp file, save it where I can get it and tell me what change you want. I will code in C# but you can follow along. Once complete, I can place it in github for others.
You can do this in SAS as well. I will lay out a flow and someone else can handle the SAS code. Since I don't have access to SAS, I can't test so no need to try.
