SECTION 1. FUNCTIONAL MODES
Sections 1.5 and 1.8 are replaced by the following sections.
1.5 MEMORY ALLOCATION -
∗A
1.5.1 INTERNAL MEMORY
When powered up with the keyboard display
attached, the CR10KD displays HELLO while
performing a self check. The total system
memory is then displayed in K bytes. The size
of memory can be displayed in the
∗B mode.
Input Storage is used to store the results of
Input/Output and Processing Instructions. The
values stored in input locations may be
displayed using the
∗6 Mode (Section 1.3).
Final Storage holds stored data for a
permanent record. Output Instructions store
data in Final Storage Data Tables. The data in
Final Storage can be monitored using the
∗7
Mode (Section 2.3).
Intermediate Storage is a scratch pad for
Output Processing Instructions. It is used to
store the results of intermediate calculations
necessary for averages, standard deviations,
histograms, etc. Intermediate Storage is not
accessible by the user.
Each Input or Intermediate Storage location
requires 4 bytes of memory. Each Final
Storage location requires 2 bytes of memory.
Low resolution data points require 1 Final
Storage location and high resolution data points
require 2. Section 2 describes Final Storage
and data retrieval in detail.
Figure 1.5-1 lists the basic memory functions
and the amount of memory allotted to them.
