[3] Explanation of strings
Characters sent per the aforementioned transmission format are stored in a “string,” which,
simply put, is a dedicated container for characters.
Strings are divided into global strings that can be read or written in all programs, and local
strings that can be read or written only in each program in which the applicable string is specified.
For differentiation, both strings are assigned a column number in a different range.
One character is stored in each column comprising a string.
Positions of fields in a string are indicated by column numbers, and which columns are used to store a
given set of characters can be set freely using a command.
For example, if a character string “HOME” indicating a home return command is to be sent from the PC for
use in multiple programs, “HOME” must be specified for storage in columns starting from 300.
