>You're confusing the location of the code with the functionality of the code. There is no benefit to the code at runtime if they are stored in a single .prg. My testing of calling separate prgs in an exe versus calling them in a function library shows there is a difference. Further there was a time when having a .prg that started with a function declaration of the same name was slower.

There is only one strong reason for doing this (bundling multiple functions into one PRG), and it would be to implement abstraction / polymorphism.
You would create the same function in two different PRGs:
EmployeeProgs.PRG -> FUNCTION Save
CompanyProgs.PRG -> FUNCTION Save
If you are in the Employee.SCX, you set procedure to EmployeeProgs.PRG
If you are in the Company.SCX, logically set procedure to CompanyProgs.PRG
Both screens can be generically calling SAVE(), while obviously the actual actions are different from each other.
So if someone were to create a procedural code, that would be the way to go. Of course it does not make sense because with OOP you have much better ways to accomplish this, but in theory that is the one case where you cannot work with separate PRG's.
