Numeral Setting Section 4-8

In order to input numerical values using the numeral setting function, apart from
the display area for the numeral setting, the numeric keys must also be created.
Setting Screen Attributes The type of numeric keys can be selected using the numeral setting attributes of
the screen attributes. There are two numeral setting attributes: “system” and
“user”.

played. The display position and arrangement of the numeric keys are fixed. On
this screen, only the types of numeric key shown in the figure below (system

When using the NT20S with the numeral setting attribute set to “system”, apart
from the numeric keys provided by the system, the touch switches allocated to
system keys ( , , ) also have to be created (system key function). To enable
input of hexadecimal values, it is also necessary to create numeric keys A through
F.
With the NT20S, if the numeral setting attribute is set to “system”, apart from the
numeric keys prepared by the system, the touch switches allocated to system
keys ( , , ) have to be created. (“System key functions”, page 139)

Tank A Tank B Tank C
When the numeral setting attribute is set to “user”, numeric keys are created by
using the control keys of the “input key” function. In addition, by using the char-
acter keys of the “input key” function, the one-byte characters 0 to 9 and A to F
can be used as numeric keys.
