program will be automatically loaded and run
when the CR510 is powered up. (If a Storage
Module with a program 8 is connected when the
CR510 powers-up, the Storage Module program
8 will be loaded into the CR510 and become the
active program.)
The active program can be stored in internal
flash memory program storage with
∗
D
command 6 (Table 1.8-3). Programs can be
retrieved with
∗
D command 7 (Table 1.8-4).

You may now enter one of the following options:
xxA Save active program as
number xx, xx may be 1-98.
A Scroll forward and
B backward through saved
program numbers. The
numbers are displayed in the
order saved.
99A99A Clear all saved programs.
0A Display number of bytes free in
saved program area.

You may now enter one of the following options:
xxA Retrieve program number xx
(the most recent xx saved). To
have the program compile like
∗
6 (no resetting of input
locations, flags, or ports) press
C (xx--) before A.
0A Erase active program (i.e., load a
blank program; memory allocation
and Final Storage are reset).
A Scroll forward and
B backward through saved
program numbers.
Scrolling through the program names begins
with the oldest program. "A" advances to the
next newer program, "B" backs up to the next
older program. While scrolling, at any time
typing in a number (xxA) will cause a save or a
retrieve operation.
Each program saved takes up the memory
required for the p 6 bytes.
Flash memory can only be written to once
before being erased. Because it can only be
erased in 16K blocks, if one stored program is
to be erased, all must be erased. To allow
revising a program and storing it with the same
number (name) as an earlier version, the same
number can be used by more than one saved
program. When retrieving a program, the
programs are searched beginning with the last
program saved; the most recently saved version
will be retrieved. An older program with a
duplicate name cannot be retrieved. When the
flash program memory is full, all programs must
be erased before any more can be added (error
94 will be displayed).
1.8.2 PROGRAM TRANSFER WITH STORAGE
MODULE
Storage Modules can store up to eight separate
programs. The Storage Module and
Keyboard/Display or Modem/Terminal must both
be connected to the CR510. After keying
∗
D, the
command 7N, is entered (N is the Storage
Module address 1-8, Section 4.4.1). Address 1
will work with any Storage Module address; the
CR510 will search for the lowest address Storage
Module that is connected. The command to
save, load, or clear a program and the program
number (Table 1.8-5) is entered. After the
operation is finished "13:0000" is displayed. Error
96 indicates that the Storage Module is not
connected or the wrong address was given.
