"ABCDE"
• Character strings in the devices specified by (s) and (d) up to a device that stores 00H are concatenated.
• When character strings are concatenated, 00H indicating an end of the character string specified by (d) is ignored and the
character string specified by (s) is concatenated to the last character of (d).
