■Descriptions, types, and data types
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
• 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).)
