Snap on for new function
FunctionPac provides an excellent vehicle for installing a new set of functions on top of existing systems. Examples of snap-ons are Netview and its related products, language products, etc. FunctionPac comes in a separate SMP/E environment (global, target and dlib), thus avoiding any interference to your existing system.
