This is a pipe. Data is available only when it has been filled by the other side. So Eof() can returns true at anytime, even if some data may be written in the future. Gambas cannot read the future yet. > if i change to > WHILE TRUE > > i get the ls results to console and > i get an error > > System error. Inappropriate ioctl for device. The error message is not very accurate. But it is normal, as reading on a pipe that has been closed on the other side is impossible.
