• In linking, "00H" indicating the end of a character string specified in
specified in
When a character string is linked, "00H" is automatically added at the end.
- When the number of characters after linking is odd, "00H" is stored in the high-order byte of the device storing
the last character.
- When the number of characters after linking is even, "0000H" is stored in the device after the last character.
