Explanation of function and operation
This function converts string data stored in a device specified in
obtained by conversion to a device specified in
'0'
'12'
String data
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 string data.
Use global labels when specifying labels.
