■Descriptions, types, and data types
Argument Description
EN Execution condition (TRUE: Execution, FALSE: Stop)
s(IN) Input
n1(L) Specification of number of characters to be extracted
n2(P) Specification of head character position of a character string to be
extracted
ENO Output status (TRUE: Normal, FALSE: Abnormal)
d(MID(_E)) Output
Processing details
■Operation processing
• These functions output the data for the specified number of characters from an arbitrary position of a character string input
to (s).
• The value input to (n1) specifies the number of characters to be extracted.
• The value input to (n2) specifies the number of the head character position of a character string to be extracted.
Ex.
When the value input to (n1) and (n2) is 5
(s)
"ABCDEF12345"

(1): Head character position of a character string to be extracted n2: 5th character
(2): Number of characters to be extracted n1: 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).)
