S Direct reference and indirect reference
Direct reference is a method whereby the memory table whose contents are to
be displayed is specified directly.
NT31/NT31C
0 0 6 2
In indirect reference, the numeral memory table whose contents are to be dis-
played is not specified directly: the contents of the specified numeral memory
table (a numeric value) are regarded as the number of a numeral memory table,
and the contents of this numeral memory table are displayed. Note that more
processing time is required for indirect reference that for direct reference.

S Number of digits displayed
All contents of numeral memory tables are stored as integers. To display a nu-
meric value that has a decimal fraction, set the "decimal" setting to "1" or higher
to specify the number of places after the decimal point, then a decimal point is
automatically inserted.
Note that if the number of digits of the numeric value is greater than the total of
the settings for "Integer" and "Decimal", an error occurs and "∗" is displayed for
all the digits.
An example is given below (here, the check mark is assumed to be set for "Zero
Suppression").
