Section 5-2
5-2 Memory Tables and Bar Graph
This section describes allocation of the memory table to PC words, and changes to
the contents of words necessary to display characters, numerals, and graphs by
communicating with the PC using the host link/NT link.
For the functions relating to memory tables and bar graphs, refer to 4-4 Memory
Tables (page 81) and 4-5 Bar Graphs (page 83), respectively.
Writing Words to the Character-String Memory Table
Since the character-string memory tables can be allocated to the words in the PC,
the PC can write data to the character-string memory tables or the initial values
can be set when creating the screen data.
