A DIAGRAMATIC EXPLAINATION/REVIEW
=For general distribution=
By John J. Gaudreault 72067,3046
Letters in "( )" = DIRECTORY (DIR)
Numbers after E's = # of ENVIROMENTS (ENV)
ENV #1 = active ENV in this diagram and,
DIR(A)=ENV1,DIR(B)=0 ENV,DIR(C)=ENV1+2,DIR(D)=ENV1+2+3.

The WORKSPACE (WRKSPC) is the 32K RAM of the M100.
Each and every DIR can access the ROOT DIR and the
"currently loaded" WORKSPACE.
Each ENV has only one WRKSPC assigned.
There is only 1 ROOT DIR and 1 NULL ENV.
All DIRs are accessible at all times.
Each members of a collection of ENVs, could each share
the same ROM, each have a different ROM or no ROM.
Each ENVIROMENT has a particular WRKSPC associated
with it, and a set of files (.BA,.CO,.DO) can be
associated with the WRKSPC/ENV.
An ENV ROM can be loaded from more than one DIR
if it has been "assinged" to that DIR, but the ENV ROM
can be "entered" from any DIR via a macro.
BASIC, TEXT and TELCOM are in DIRs only, and not in
the WRKSPC.
For proper operation ENVs should be created only in
DIRs other than the ROOT DIR, this is important!
