Numeral Memory Table Display Examples
• When the Data Is Numeral Data (0 to 9)
• When the Data Contains Characters (A to F)
If the hexadecimal data (A to F) are stored when the decimal display has been
set, the alphabets are displayed.
If the number of display digits has been set to be smaller than the maximum
number of digits of the registration words (4 digits for 1 word; 8 digits for 2
words), the contents of the allocated words are not displayed and “
*
” symbols
will be displayed at all digits.
If the most significant digit is “F” when “decimal with signs” has been set, the
numeral is handled as a negative number. The maximum number of digits of
the negative number becomes smaller than that of the positive number by 1
digit.
The actual display will vary according to the “zero suppress” setting and deci-
mal fraction setting as well as the contents described above. Refer to the “NT
Support Tool for Windows Operation Manual” (Cat. No. V061-E1-
@
).
• Contents of the Character-string Memory Table
A character string is stored in the allocated words beginning with the first
word in normal-size characters.
Two normal-size characters are stored in one word. One memory table en-
try can store up to 16 words (32 characters).
Character-string Memory Table Display Example
To display the characters in order, allocate the characters as follows:

Changing Displayed Numerals or Character Strings
(Changing the Contents of Allocated Words ... Direct
Specification)
The following explains the actual procedure for changing the contents of allo-
cated words referenced by direct specification in order to change numerical
values and character strings displayed by the NT20.
For the situation when using indirect specification, refer to
5-2-3 Changing
Displayed Numerical Values or Character Strings (Changing the Contents of
Allocated Words ... Indirect Specification)
on page 184.
Numerals and character strings can be changed also by making a copy of the
memory table entries. Refer to “Copying Memory Table Entries,” below.
