Look at SECURTY2.ASM in MICRO:<CPM.RCPM>.  This is assembled and
renamed to RBBS.COM and placed in user zero.  The "real" RBBS and all
its files are placed in a user area that is inaccessable to callers.
SECURTY2 is a small loader program which switches user numbers and
then loads RBBS and jumps to it.  When the user exits RBBS they return
to the original drive/user because the user number change was only
temporary.
