FIGURB 2 - VECTOR 4 CP/M'S LOGICAL STRUCTURE
When
.you
enter a command, the Console
Command
Processor (CCP)
checks your entry against the Resident Commands. If your input
matches one of these, the result of the command (for instance,
DIR
for directory) is displayed on the screen. If
you
entered something
else, the CCP looks
at
the directory
on
your drive. (If
it
can't
find
what
you
entered,
it
prints your entry followed by a question mark.)
The program
you
called is found
by
the Basic Disk Operating System
(BOOS)
and
sent
to
the Transient Program Area
(TP
A),
through lines
opened by the Basic Input/Output
System
(BIOS).
The Transient
Program Area stores and
runs
the program. The results
of
the
program
are
displayed
on
the screen, and any
new
data
are recorded
by the
BOOS.
