Function
The string from head address [S2] is appended to the string from head address [S1]. The resulting string is
stored in [D].
The characters in [S1] and [S2] are organized byte by byte. The rst 00H byte indicates the string end.

00H ignored
The 00H that indicates the end of a string is ignored and the last character of this string is connected to a
designated string. 00H is automatically appended to the new string.
• When the number of characters contained in the new string is odd, 00H is stored in the higher byte of the element
that stores the last character.
