Area where operation results are stored
Description
The number of characters specified by “S2” is searched starting from the left side (the beginning of the
character data) of the character string specified by “S1”, and is sent to the character string specified by “D”.
At the starting address of the area for storing results “D”, designate the character string size using the user
program.
Precautions during programming
The character data from “D” prior to the operation is cleared.
If the number of characters specified by “S2” is larger than the number of characters in the character string
specified by “S1”, the number of characters of the character string specified by “S1” is sent.
If the number of characters specified by “S2” is larger than the size of the character string of “D”, data equal to
the size of the character string specified by “D” is sent.

・Error flag (R9008): Turns on for an instant when:
− The specified range is exceeded when an index is modified.
− The number of characters is larger than the character string size.
・Carry flag (R9009): Turns on for an instant when the result of the operation is larger than the size
of the character string specified by “D”.
