• This instruction stores the NULL code (00H) into the device (one word) that positions after the last device that stores the
character string data when the character string data specified by (D) is even, after the characters are deleted.
• This instruction stores the NULL code (00H) into the last device (high 8 bits) that stores the character string data when the
character string data specified by (D) is odd, after the characters are deleted.
• This instruction shifts the characters stored in the devices that position after the deleted devices by n2 characters to the
right, and then stores the NULL code (00H) into the empty device.
