When displaying the contents of numeral memory tables that are allocated to
host words, not only the numeral display properties but also the “Storage Type”
and “Words” settings made for the numeral memory table have an effect on the
permissible display range. The permissible display range is determined as fol-
lows depending on these properties.

displayed when the contents of the numeral memory table are 8000

−
32768),
and 2147483648 is displayed when the contents of the memory table are
80000000H (
−
2147483648). This is because when the value is unsigned, only the
sign is omitted and the numeric value is displayed as an absolute value. It is not
possible to input 32768 or 2147483648 as positive values.
