devices required to store extracted "n" characters (that is, when "00H" cannot be stored after all character
strings and the last character) (error code: K6706)
• When "n" is a negative value (error code: K6706)
Program example
In the program example shown below, the number of characters which is equivalent to the number stored in
D0 are extracted from the left end of the character string data stored in D100 and later, and stored to R10 and
later when X010 turns ON.
