Allocate character string memory tables to arbitrary words in the PC. If the word
contents change when the corresponding character string memory table is dis-
played on the screen, the character string on the screen will also change. Any
messages can be displayed easily.
Reading and writing are executed so that the contents of allocated words are
always the same as those of the character string memory tables.

automatically cleared.
