Simple words? Please see the following: Ansys Help -> Mechanical APDL -> Programmers Reference -> Part II Guide to User Programmable Features.
User Programmable Features = UPF. Typically a UPF would be something like implementing a new element type or material model. If you really only need to get a list of nodes and their positions, perhaps saved to a file, then it is much more efficient to do that with APDL than a UPF. Or really most of the FEM data is fairly easy to get via APDL. So the real question is, what do you really want to do?
