Explanation of function and operation
1. 16-bit operation (RIGHT and RIGHTP)
"n" characters are extracted from the right end (that is, from the end) of the character string data stored in
later, and stored to
If the number of characters specified by "n" is "0", the NULL code (0000H) is stored to
When characters are extracted from a character string, "00H" is automatically added at the end of the extracted
characters.
- When the number of extracted characters is odd, "00H" is stored in the high-order byte of a device storing the
last character.
- When the number of extracted characters is even, "0000H" is stored in the device after the last character.
