Try adding the FILE_READ statment to it as in:

int handle = FileOpen( FileName, FILE_CSV | FILE_READ | FILE_WRITE, ";" );

CockeyedCowboy

I have already tested it, but this syntax cause same result

anyone know if you can import settings from a file and assign them to a var in an expert?

of course, you can use FileOpen(FileName,FILE_CSV|FILE_WRITE,";"); for prewrited file then use related reading syntax such as FileReadArray,FileReadString, ....

thank you very much lowphat, the file that you have attached was so usefull, this program, use FileTell Syntax to find pointer position, and then use the FileSeek to Set the pointer position of file, so the new data can be writen right after the last ones
