6-4-4 Initializing the Memory Tables
It
is possible to initialize the numeral memory table and
character string memory
table in the NT21.
When
these tables are initialized, the values are returned to those set
by the NT
Support Tool (they are not cleared).
When
the memory tables are initialized, they are returned to their initial
values
regardless of the setting made for the resume function (page 140).
If
ON
is set for the Resume Function memory switch, the initial values set with
the NT Support T
ool will not be recorded in the memory tables unless they are
initialized.
