S "Initial" setting and initial value
The "Initial" setting determines whether the contents of numeral memory tables
are written to the allocated word(s) at the host when the power to the
NT631/NT631C is turned ON, when the NT631/NT631C is reset, or on transition
from the System Menu to the RUN mode.
Here, "Initial" (initialization) means the initialization of the contents of host
word(s) as they are overwritten by the contents of the numeral memory table. If
the numeral memory table is not allocated to a host word or words, this setting
has no effect.
When the NT631/NT631C starts operation, the contents of numeral memory
tables is as follows depending on whether or not the numeral memory table is allo-
cated to the host, on the "Initial" setting for the numeral memory table, and on
whether or not the resume function is used.

Numeral memory tables themselves have no display function.
To display the contents of numeral memory tables, use 7-8 "Numeral Display"
(page 348) or 7-10 "Graphs" (page 362).
When a numeral memory table is allocated to a word or words at the host, the con-
tents of the word are read and stored.
However, reading is only executed for those numeral memory tables that are being
used for the currently displayed screen (when copying a memory table, the con-
tents of the allocated word(s) of the copy source memory table are read).
