Processing details
■Operation processing
• These functions concatenate the character string input to the input variables (s2) to (s28) after the one input to (s1) and
output the result from (d).
• When character strings are concatenated, 00H indicating an end of the character string specified by (s1) is ignored and the
character string specified by (s2) to (s28) is concatenated.
• When the concatenated character string exceeds 255 bytes, these functions output a character string within 255 bytes.

3rd word 3rd word 00H 00H 45H (E) 45H (E)
• A value input to the input variables (s1) and (s2) to (s28) is the STRING type data value and within the range from 0 to 255
byte(s).
