Input of Numeric Values and Character Strings
Section 8-7
8-7-2 Inputting Character Strings
To input a character string, the touch switch “input key – string” is used. Basically,
the “input key – string” arranged on the same screen is used to directly input a
character string into a character string input field. It is also possible to use “input
key – string” or a “temporary input field” registered for a “window”.
Registration of more than one character string input field in a screen is permitted.
To specify the objective input field among multiple input fields, either the “input key
– control” provided for shifting between input fields or a cursor moving key should
be used.
When inputting a character string, the specification of an input field, window open-
ing procedure, and the major purposes of a temporary input field are identical to
those for inputting a numeric value. The explanation below concentrates on how a
character string is input; other information is not discussed. For the procedure for
specifying an input field and opening a window, and for the major purposes of a
temporary input field, refer to the corresponding items in the description of the op-
eration for “numeric value input”.
In character string input operation, bar code data can be input as a character string
using a bar code reader which is connected to the NT31/NT31C.
Only the following topics are described here.
- Using the “input key – string” on the same screen
- Using a bar code reader

Restrictions specific to character string input when using temporary input fields
When inputting a character string, a temporary input field can be used as for in-
putting a numeric value. But when using a temporary input field for inputting a
character string, the following specific restrictions should be noted.
- When inputting a character string, the temporary input field must also be the
character string input field.
- Even if the number of digits of a temporary input field is smaller than the num-
ber of digits of the objective input field on the base screen, the temporary input
field can be used to input a character string. In this case, however, blank digits
remain in the character string input field on the base screen and these blank
digits are filled with spaces. In the initial display, characters which overflow the
temporary input field are disregarded.
- Even if the number of digits of a temporary input field is larger than the number
of digits of the objective input field on the base screen, the temporary input field
can be used to input a character string. In this case, however the input charac-
ter string will overflow the character string input field on the base screen and
the overflowing characters are ignored.
- A temporary input field is not displayed if an input field does not exist on the
base screen.
