Outline
This function converts word [signed] data into string data, and outputs the data obtained by conversion.

Explanation of function and operation
1) This function converts word [signed] data stored in a device specified in
into string data, and outputs
the data obtained by conversion to a device specified in
.
2) In "Sign data", "20H (space)" is stored when the input value is positive, and "2DH (-)" is stored when the
input value is negative.
3) "20H (space)" is stored in high-order digits when the number of significant figures is small.
Example: When "-123" is input
4) "00H" is automatically stored at the end (4th word) of the character string.
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 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.
