7.8 String Processing Instructions
• These instructions read data by the number of characters stored in the device specified by (s2)+1 from the character string
data stored in the device number specified by (s1) and later, and store the read data at the location in the device specified
by (s2) and later in the character string stored in the device number specified by (d) and later.
• The NULL code (00H) indicating the end of a character string is automatically added to the end of the character string data.
• If the number of characters in the device specified by (s2)+1 is 0, no processing is performed.
• If the number of characters in the device specified by (s2)+1 exceeds the last character of the character string data in the
device specified by (d), the data is stored up to the last character.
