All,

I was checking out some of our user XLs (libraries we provide with our
product) and was horrified (well, not that extreme) to find that there were
system entry points listed in our user modules.  Examples are Image calls,
NetIPC calls, and calls like FOPEN, IOWAIT.....

Now, I noticed that LINKEDIT shows these as "stubs external" so maybe we are
not really loading system routines into our user libraries (whew).

So, am I safe to assume that these system entry points shown as "stubs
external" are merely references to those entry points in the system
libraries, included merely for the benefit of the user routines (in the
module) that call them?

What's the technical skinny on this?  Perhaps I should RTFM?
