Note
● The files must not be in the file system of the NC (data management).
● If the file does not exist, or the end of the file is reached or other errors occur, the variables
FILE_ERR and ERR are set accordingly. You can check whether a file exists first with the
Exist Program (EP) file function.
● The processed file is generated in "UTF-8" coding (without BOM (Byte Order Mask). When
reading a file, it is expected in "UTF-8" coding.
● You can delete the file explicitly when required with the Delete Program (DP) file function.
