Argument Description
EN Execution condition (TRUE: Execution, FALSE: Stop)

Processing details
■Operation processing
• These functions delete the data for the specified number of characters from an arbitrary position of a character string input
to (s) and output the remaining character strings from (d).
• The value input to (n1) specifies the number of characters to be deleted.
• The value input to (n2) specifies the number of the head character position of a character string to be deleted.
Ex.
When the value input to (n1) and (n2) is 5
(s)
"ABCDEF12345"
High-order byte Low-order byte
1st word 42H (B) 41H (A)
2nd word 44H (D) 43H (C)
3rd word 46H (F) 45H (E)
4th word 32H (2) 31H (1)
5th word 34H (4) 33H (3)
6th word 00H 35H (5)
• A value input to (s) is the STRING type data value and within the range from 0 to 255 byte(s).
• A value input to (n1) is the INT type data value and within the range from 0 to 255. (However, the value must be within the
number of characters of the character string to be input to (s).)
• A value input to (n2) 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 (s).)
