#menu# remove a DDA device from the VP/ix Environment
#help#
#help#  This procedure allows you to "deregister" a device that was
#help#  previously installed for Direct Access in the VP/ix Environment.
#help#
#help#  Once a device has been deregistered, VP/ix users may no longer
#help#  request access to it by specifying its name in their vpix.cnf files.
