Operating Instructions
5.1.4 List element fields
This type of data entry is where a pre-defined list of available data values are available to the
user who must select the one which is applicable. Free-format text is not allowed.
5.1.5 Incremental value fields
These are fields where a value is displayed on the screen and the user has the option of
increasing or decreasing the value.
5.1.6 Data entry input errors
After entering data for a field, the system will verify the validity of the data. For example, if a date
of 41/12/07 is entered, the system will not accept it. If any field is found to be invalid, an
appropriate error message will be displayed at the bottom of the screen and the system reverts
back to the original value for that field.
Press one of the Up Arrow function keys to acknowledge the error, and re-enter the data, or
Esc
to acknowledge the error and exit the screen.
The highlighted field in the example left is a data
element where there is only a limited number of valid
options (i.e. the seven days of the week).
For data elements such as these, press the function
key under the Up Arrow option to scroll forward
through the pre-defined list (in this example Tuesday,
Wednesday, Thursday...) or press the function key
under the Down Arrow option to scroll backward
through the list.
When the required list element is displayed press the
Enter
function key to accept the data and move to the
next data input field.
In this example, the whole value, rather than an
individual digit, is highlighted.
Use the Up Arrow function keys under the plus or
minus symbols to increase or decrease the value by 1.
On completion press the Enter function key, to accept
the new value.
