The names of the bits and words that are allocated to the PC at the NT-series
Support Tool, and the areas for each PC model, correspond in the following way.
The types of area that can be allocated to display elements depends on the type
of display elements. For details, refer to the explanations of the allocations for
each type of display element in this section. The range of respective area varies
with the type of PC. Refer to Appendix J PC Memory Maps (page 293).
The allocations must be made without exceeding respective area range.

When allocating memory table entries to words, the allocation must not exceed
the word area.
The Auxiliary Area of a CV-series PC is allocated to the system and cannot be
used for purposes other than the system use. However, reading from this area is
possible.
One allocation for a memory table entry can use up to 2 consecutive words in the
case of numeral memory table entries or 16 words in the case of character string
memory table entries.
