INPUT OF DATA
General
All input of data begins at the LCR Main Menu. The
LCR Main menu provides various functions which the
programmer can access by selecting a number. After
the programmer makes a selection, the CR (RETURN)
key is depressed and the program to access that
selected function is loaded from the floppy disk into the
computer. A new menu is displayed allowing the
programmer to select the desired table. Again a
number is selected from the menu and the CR key is
depressed. The data for the chosen table is loaded from
the floppy disk into the computer. At this stage in
programming, various options may be available
depending on which function was chosen from the LCR
main menu. The data may now be modified, displayed,
or printed.
From the information above, it is apparent that a
keystroke serves two functions; a command function,
and data function.
From the menu, a selection number, followed by a CR
(RETURN), obtains the program for a specific function,
or retrieves data for a specific table. After table data is
displayed, usage of the keys changes data, permits
movement through the table to obtain specific data, or
to enter new data.
To exit a table, depress the ESC (escape) key. Data for
that table is saved to the floppy disk (MODIFY MODE)
and the previous menu is displayed. Depress the ESC
key again to return to the LCR main menu, or select a
new number and depress CR (RETURN) to retrieve
another table.
As an aid in understanding the programming
procedure, refer to Figure 700-29 General
Programming Flow Diagram. This diagram provides a
general overview of the programming procedure.
As shown in the diagram, eight functions are available
from the LCR Main Menu. Only one function (or
operational mode) may be used at any one time. The
use of a second function is only available by returning
to the LCR Main Menu.
After a function is selected, a new menu is provided
(except SYSTEM CONTROL) where a table type can
be selected. Selecting SYSTEM CONTROL from the
Main Menu sends a reset signal to the LCR-E ETU
allowing return to the Main Menu. After selecting a
table type, different operations are available based on
the function selected.
Refer to section 750.8-l for an explanation of the LCR
Main Menu and a brief description of the eight
available functions.
Section 750.8.2 provides a detailed explanation of each
function as related to the programming procedure.
The DOWN LOAD, UP LOAD and Verify functions are
used for the maintenance function where data is
transferred to and from the LCR-E ETU and the LCR
disk.
The MODIFY MODE is used to customize the data, for
a specific application, on the LCR Disk. The DISPLAY
MODE is used to examine data without changing data.
(This is similar to the MODIFY MODE but runs faster
because no changing or saving of data is done.)
PRINTOUT is used to retrieve a printed copy of the
system data. SYSTEM DATA CLEAR is used to clear
the data on the disk that is no longer desired.
