Re: What the beep is wrong with this?

Hi Jon, if I'm not wrong open has 5 parametrs not 4.

Anyway the most common error using textdata is this one:

If O_CCSID is not specified, and the file CCSID and open CCSID are not the
same, and one of them is not strictly single-byte, open() will fail with
errno set to [ECONVERT].
