Returns a number representing the position of an I/O device in the I/O Device repository. This is the I/O device that Magic xpa is currently being printed to.

Returns:

A number representing an entry in the I/O Device repository.

Note:

This function can only be used when an I/O is actually in process. This means that this function can be used for Event expressions or within the Event tasks that are spawned by the Page Header and Page Footer internal events. This function returns the I/O number only when you have assigned page header or page footer forms to the graphic printer. Otherwise the function will return 0.
