Usage Notes: - Language Environment maintains
a list of all modules loaded by the low-level load service. This list
is maintained so that Language Environment can delete
all modules it loaded with the low-level load service during the life
of the environment.
- If more than one load is issued for a module, multiple loads are
not performed. For the first load request, the module is brought into
storage. If any subsequent load requests are made for that module,
its address is returned and a use count is maintained for it.
- If a delete request is made, the use count decrements and, when
it reaches zero, the module is deleted from virtual storage.
- It should be noted that calling a deleted entry point is an error
and causes unpredictable results.
