List lines
List lines are used to select a value. You do not enter the value directly, but identify it with a
keyword selected from a predefined list specific to the MMC.
This gives better control over entering values (no errors are possible). The system also manages
a list of prohibited values which can be different for each field referring to the same list.
When you position the cursor on this type of line, the list element displayed changes to reverse
video. The following commands are used to scroll through the list elements: Space bar,
Backspace, and Delete key.
In some lists, the required keyword can be obtained by entering the first few letters of the
keyword. It is then displayed in full. An error message signals an empty search result. This
selection mode is only available on the empty element ("......."). The commands must then be
preceded by the Esc key.
Types of menu and types of line
The following table gives the various types of line possible for each type of menu:
* Under certain conditions
Commands
The operator uses the commands described below for navigation through the various screens
using the cursor.
Some of the commands are available in all the menus, some are specific to a type of menu
(repetitive menu), and some are temporarily masked according to the type of screen in use (a
screen with no data entry fields).
When the cursor is in an ASCII data entry field, press the Esc key to activate the command mode
before entering commands in ASCII form. The Esc key can be used before any command.
The commands described below are for a VT100 terminal. The table in the following section
gives the correspondence between the VT100 commands and the Minitel (videotex) commands.
