I/O Device Number - Form Input Operation (Magic xpa 4.x)

This I/O Device Identification Number is required. It specifies the number of the I/O device, as it appears it the I/O Device list, from which you want to read. Its default setting is 1, the first device.

The I/O device you specify must have its access property set to Read. See I/O Device Repository for more information.

You can specify a file defined (that is, opened) in an ancestor of the current task. If you need to define a new I/O device, zoom from the I/O Device list into the I/O Device repository.

Zoom to the I/O Device list and select the file that you want.
