5-3 Common functions (Basic)

These functions can be used in common.

Character string processing functions

Reader status acquisition functions

*1 When the Master/Slave function is used, result data cannot be obtained correctly.

Debug function

*2 The output setting turns ON after the "SCPDBG,1" command is executed. "6-1

Debug methods" (Page 13)

Function name Argument Return value Applicable model

left (str, m)

str: character string

m: number of digits

(1 to 9990)

Character string of m digits

counted from the start of the

character string (str).

mid(str, s, m)

str: character string

s: 1 to 9990

m: 1 to 9990

Character string of m digits

counted from s digit position

from the start of the character

string (str). If m is not specified,

the range from the start position

(s) to the end is specified. If the

start position is outside the

range of character string data,

there is no return value.

right(str, m)

str: character string

m: 1 to 9990

Character string of m digits

counted from the end of the

character string (str)

field(str, m, sep)

str: character string

m: 1 to 9990

sep: character

(1 character)

The mth character string after

dividing the character string

(str) with the separator (sep)

Function name Argument Return value Applicable model
