While entering a value, the value may be edited using the
[backspace] key. This key will remove the right most digit (or
decimal point or negative). The help screen uses the backspace key
to return to the previous level of help.
The enter key varies depending on the screen. If you are in the
process of a selection operation, the enter key will accept the
selection and proceed to a different screen based on the selection in
order to complete the operation. If you are in the process of entering
data, the enter key will accept the edited data.
What is a Screen?
The operator interface uses menu driven screens to perform various
operations on the drive. You can think of a screen as a window or
template, overlaying data from the drive. The operator interface
combines a screen with the drive data, to formulate what you see on
the display area of the operator interface. Individual screens display
a particular type of data and allow selected operations to be
performed on this data. A number of different screens may be used
while performing a single operation.
Components
Although the data displayed on any particular screen will vary, the
general makeup of a screen is the same for all. Figure 3.2 shows a
typical screen and its components.
