Cautions
This instruction can handle character codes other than ASCII codes, but please note the following:
• The number of characters is handled in byte units (8 bits). Accordingly, in the case of character codes in which 2
• The number of characters 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 code, the length of 1 character is regarded as 2 characters.
• When overwriting a character string including character codes in which 2 bytes express 1 character such as shift
JIS codes, consider the number of characters to be extracted in units of character codes for 1 character.
Note that the expected character code is not given if only 1 byte is overwritten out of a 2-byte character code.
Note that the expected character code is not given if only 1 byte is overwritten out of a 2-byte character code.
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
D8067.
• When “00H” is not set within the corresponding device range after a device specified by
or
(error
code: K6706)
• When the value specified by
exceeds the number of characters of the character string stored in
and
later (error code: K6706)
• When the number of characters specified by
+1 exceeds the number of characters specified by
(error
code: K6706)
• When
specifies a negative value (error code: K6706)
• When
+1 specifies “-2” or less (error code: K6706)
Program example
In the program example shown below, 4 characters are extracted from the character string data stored in D0 and later,
and stored to the 3rd character (from the left end) and later for the character string data stored in D100 and later when
X010 turns ON.
