Menu definition and management
Each menu has up to four sections:
• a message bar for information and error messages
• the name of the menu
• lines of data options
• a box indicating keystroke commands
To ensure complete compatibility between Minitel (videotex) and VT100 terminals, the length of a
display line is limited to 40 characters.
Note: A menu consists of 1 to 8 screens. Each successive screen displays the name of the
screen and the keystroke commands.
Information or error messages
These messages are displayed in the centre of the first line on the screen, in reverse video and
blinking. They appear when an error is detected. It is cleared by pressing any key.
Name of the screen
The name of the screen serves as a reference, indicating in which screen you are working. It
consists of a single line and is displayed in the centre of the second line on the screen, in reverse
video and double height. On a VT100 type terminal, it is displayed in double width. The name of
the screen is either fixed or context-sensitive (context-sensitive for repetitive menus).
