ACP_SWAPFLGS

   ACP_SWAPFLGS enables or disables swap through the value of a
   4-bit number for the following four classes of ACPs:

   Bit    Class of ACP

   0      Disks mounted by MOUNT/SYSTEM

   1      Disks mounted by MOUNT/GROUP

   2      Private disks

   3      Magnetic tape ACP

   If the value of the bit is 1, the corresponding class of ACPs
   can be swapped. The value of decimal 15 (hexadecimal F-all bits
   on) enables swap for all classes of ACP. A value of decimal
   14 disables swap for ACPs for volumes mounted with the /SYSTEM
   qualifier but leaves swap enabled for all other ACPs. Note that
   one has only disk ACPs present if they are specifically requested
   at mount time or if a Files-11 On-Disk Structure Level 1 disk is
   mounted. In general, only bit 3 is significant because usually no
   file ACPs exist.

   ACP_SWAPFLGS is an AUTOGEN and DYNAMIC parameter.
