■Descriptions, types, and data types
Argument Description
EN Execution condition (TRUE: Execution, FALSE: Stop)

n(P) Specification of head character position of a character string to be
inserted
ENO Output status (TRUE: Normal, FALSE: Abnormal)
d(INSERT(_E)) Output
Processing details
■Operation processing
• These functions insert the character string input to (s2) at the (n)th character from the start of the character string input to
(s1) (head position of the insertion) and output from (d).
• After the character string specified by (s2) is inserted to the one specified by (s1), 00H indicating an end of the character
string specified by (s2) is ignored.
• When the inserted character string exceeds 255 bytes, these functions output a character string within 255 bytes.
Ex.
When the value input to (n) is 4

+2 36H (6) 35H (5)
+3 00H
(1): Head character position of a character string to be inserted n: 4th character
• A value input to (s1) and (s2) is the STRING type data value and within the range from 0 to 255 byte(s).
• A value input to (n) is the INT type data value and within the range from 1 to 255. (However, the value must be within the
number of characters of the character string to be input to (s1).)
