2 Instruction Descriptions
Sample Programming
Here, multiple text strings that are separated by CR codes are stored in a file named 'ABC.csv.' All of
them are text strings of numbers. One line at a time is read from the file, the text strings are converted
to integers, and the results are stored in INT array variable InDat[]. Processing is ended when all of the
data to the end of the file is read.
It is assumed that this sample programming is in a periodic task.

3
The STRING_TO_INT instruction is used to convert the text string that was read to an integer
and store it in InDat[].
4
Steps 2 and 3 are repeated until the EOF (end of file).
5
The FileClose instruction is used to close the file.
