Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling character string data in structured programs, you cannot specify 16-bit devices directly,
different from simple projects. Use labels when handling character string data.
Use global labels when specifying labels.
Error
An operation error occurs in the following cases. The error flag M8067 turns ON, and D8067 stores the error
code.
1) When "00H" does not exist in the corresponding device range after the device specified in
(Error code: K6706)
2) When the number of characters of a character string stored in devices specified in
(Error code: K6706)
3) When the number of devices after the device number specified in
devices required for storing the character string remaining after deletion of specified number of
characters
(Error code: K6706)
4) When the value specified in
(Error code: K6706)
Program example
In this program, specified number of characters are deleted from an arbitrary position of a character string
stored in devices specified in
specified in .
