I was asked in an interview how I would go about coding a call to a
procedure so that no binding to that procedure would occur at compilation.
I said I would need to have the addresses of the callable procedures and I
would have a generic prototype based on a pointer that called the procedure
indicated by its address. Depending upon what the program needed to do I
would initialise that pointer so the right procedure would be called.
This was a test to get an idea of my RPG skills, but I discovered that this
was a technique favoured by the shop. I did not dare ask why would they
want to use this technique, so I'm asking : why would you really want to do
it this way? Why not just use a SELECT statement?
