Area where operation results are stored
Designate with the user program
Description
The number of characters specified by “S3” is retrieved starting from the position specified by “S2” in 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 “S3” is larger than the number of characters in the character string
specified by “S1” from the position specified by “S2”, the number of characters of the character string
specified by “S1” is sent.
If the number of characters of the operation result 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.
The position specified by “S2” sets the least significant byte as K0 (byte 0), and the positions are counted in
the order of 0, 1, 2, etc., starting from the least significant byte.
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・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
− The number of characters of “S1” is larger than the number of characters of
“S2”
・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”
