750.8INPUT 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.

CHAPTER 7

APRIL, 1990

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.
