Shared access of the container file or a replaced device are
 	now possible by connecting with the /SHARE switch. For this to
 	work the 'LD' devicename must be the same on all nodes of the cluster
 	which connect to the same container file or device.

 	Device geometry can now be specified by connecting a device with
 	the /SECTORS, /TRACKS and /CYLINDERS qualifiers. Also the maximum
 	usable size may be given with the /MAXBLOCKS qualifier, which
 	supersedes the /ALLOCATED qualifier.

 	An allocation class may be specified for the LD device with the
 	/ALLOCLASS qualifier for CONNECT. If this is not done then the
 	default is the value from the systemparameter ALLOCLASS.

 	A switch was added to CONNECT, /SYMBOL. This allows a DCL
 	symbol to be set representing the created unit number if it
 	was not specified.
