Caution
• This instruction can handle character codes other than ASCII codes, but the character string length is handled in
byte units (8 bits). Accordingly, in the case of character codes in which 2 bytes express 1 character such as shift
JIS codes, the length of 1 character is detected as "2".
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When "00H" is not set within the corresponding device range after a device specified by
• When the detected number of characters is "32768" or more (error code: K6706)
Program example
In the program example shown below, the length of a character string stored in D0 and later is output in 4-digit BCD to
Y040 to Y057 when X000 turns ON.
