What good is ILE??
Before ILE, if you needed to call program B from program A, a simple CALL statement did the job.
All you had to worry about was the library list and it was up to you to pass parameters correctly.
Then IBM introduced ILE.
Now you can worry about, Activation Groups,Binding Directories, Binder Language, subprocedures, service programs, Static Binding, Dynamic Binding, Bind by Reference and some I can't recall right now.
Sure, it's nice that the compile checks to ensure that passed parameters match, but what other benefits are there? The benefit isn't speed. Newer hardware resolves that.
All the complexity just increases the potential for coding errors.
So I ask great minds of the Midrange List, what good is ILE?
