Operand Description
S1
Starting device address of the string data to be searched for (available range: 0 to 65534; for
character constant: 0 to 256 characters)
p Starting search position of the string to be searched for (available range: 1 to 65534)
S2
Starting device address of the string to be searched (available range: 1 to 65534; for character
constant: 0 to 256 characters)

Outline of operation
● This instruction searches for the string data specified by [S1] in the string table starting from
[S2].
● For [p], specify the relative position (by byte) in the string table where the search starts.
● For the search result, the number of same character data is stored in the device whose
address is specified by [D], and the relative position (by byte) of the first match is stored in [D
+1].

Processing
Example 1) Searching for string "EFG" stored in DT0, in the string table from DT10
[S1]...DT0 [p]...U1 [S2]...DT10 [S2]...DT120
