But more importantly, it means that when any two of these
programs are in use at the same time (i.e. both active in the
stack) you are using twice the memory _per_user_ - if five
programs are in use that is five times the memory. Multiply
that by your number of active users and you'll see that your
memory usage (and therefore disk in terms of paging storage)
are also significantly affected by this practice.

Service programs were invented to avoid the kind of scenario
that your current practice creates. You are wasting
significant disk space and significant memory by binding by
copy instead of by reference. And you gain little or nothing.

This is just the kind of ammunition I need for my argument, thanks!

Just another thing, if the compiler needs a module to compile a program and doesn't find that module, a message is sent that indicates the name of the procedure that isn't found. Does that mean that when binding by copy, not all the procedures are necessarily copied, or is the whole module bound?
