Explanation of function and operation
1. 16-bit operation ($+ and $+P)
The character string data stored in and later is linked to the end of the character string data stored in and
later, and the linked data is stored to devices starting from .
A character string stored in or or later indicates the data from the specified device to the first "00H" in
units of byte.
• In linking, “00H” indicating the end of a character string specified in is ignored, and a character string
specified in is linked to the last character 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.
