5.1.2 Numeric fields
These fields require that the user enter one or more numeric values into a field. The type of field
determines the available input. In some fields only digits 0 through 9 would be available to
select whereas in other fields the decimal point and/or minus sign may also be available.
The highlighted field in the example left is a numerical
data element which requires input from the user.
As this is a date field, only digits 0 through 9 will be
available for selection.
For data elements such as these, press the function
key under either the Up Arrow or Down Arrow options
to initiate data entry.
The first digit will then be highlighted, and a new Right
Arrow
option replaces the Select option at the bottom
of the screen.
Press the function key under the Up Arrow option to
increase the value of the field by 1.
Press the function key under the Down Arrow option to
decrease the value of the field by 1.
Press the function key under the Right Arrow option to
accept the currently displayed digit and move one digit
to the right (i.e. 5 in the example left).
Press the Enter function key to accept the data and
move to the next input field.
It is not necessary to enter data into each of the
available data elements that make up the data field.
For example, if it was required to simply change the
date from the 25/07/07 to 25/08/07, the following steps
are all that are required:
• Press the function key under the Right Arrow
option until the digit 7 is highlighted.
• Press the function key under the Up Arrow option
to increase the value of the field by 1 to 8.
• Press the Enter function key to accept the complete
data field (25/08/07) and move to the next data input
field.
