That's just the way the language works. I don't particularly like that "feature", either. And no, you don't need to USE IO(0). Off the top of my head, I can't think of any reason an application programmer would need to reference IO(0).
Incidentally, when %ZIS was designed, the primary use for device output was printing reports. If you ever need to use multiple devices, you should look at ^%ZISUTL. I find these calls useful, for example, in working with network devices. --- Kevin Toppenberg <[EMAIL PROTECTED]> wrote: > Greg, > > Thanks for your help. > > I don't understand why the use only works for the current line.... oh > well. > Do I need to put a U IO before every write in the REPORT function? > If the system reverts to the home device on the next line, do I need > to U IO(0)? > > Thanks > Kevin > > > Greg Woodhouse <[EMAIL PROTECTED]> wrote: > Very close.
