One allocation word of the memory table can use continuous areas of up to 2
words in the case of numeral memory table or 20 words in the case of character-
string memory table.
When allocating a memory table to words, the allocation must not exceed the
word area.

they cannot be used for purposes other than the system use. However, reading
from them is possible.
