Lines of data options
A set of a maximum of 128 lines constitutes the menu text. These lines are displayed with no
special effects. The block of text is displayed in the centre of the screen. It may be divided into 1
to 6 screens, each containing 16 lines. There are two major line families: simple lines and lines
with a data entry field.
Keystroke commands
The keystroke command box indicates the keystroke commands that can be used in the screen.
It displays 1 to 4 lines with special effects on the relevant letters of the words. Only the
commands are displayed, no explanation is given. A word printed between the signs "<" and ">"
refers to a key. A capital letter refers to the key to press to run a command.
Types of menu
There are seven types of menu:
• choice menus
• password menu
• selection menus
• intermediate data entry menus
• data entry menu
• repetitive menu
• display menu
These menu types can be divided into two families:
• intermediate menus (choice, password, selection, intermediate data entry)
• terminal menus (data entry, repetitive, display)
Confirming an intermediate menu always leads to another menu (intermediate or terminal).
Terminal menus end the tree structure (last menu).
Choice menu
Choice menus are displayed on one screen. They contain a maximum of 15 different choices.
The choices are numbered 1 to n. The last line is reserved for entering your choice. If you make
an invalid choice, an error message is displayed. If you make a valid choice, the next menu in the
tree structure is displayed.
Password menu
Password menus are displayed on one screen. The data entry line prompts the operator to enter
a password. The characters of the password are not displayed. They are replaced by asterisks
(
∗).
If you enter an incorrect password, an error message is displayed. After three consecutive
errors, the password attempt is treated as a fraudulent attempt to access the system. This blocks
the system for a few minutes and a report is entered in the log. If you confirm a correct password,
the next screen in the tree structure is displayed.
