LD CONNECT file_or_device [LDAn:] [Logicalname]

 	This command will connect the Logical Disk File to the Logical
 	Disk device.

 	This function must be performed before the logical disk can be
 	mounted or otherwise used. It requires the Physical Disk to be
 	mounted and requires read and write access to the Logical Disk File.

 	If the LD-device is not specified, it will be assigned by the
 	driver, and an informational message will be given about which
 	device is selected.

 	If the LD-device is not specified and a file is connected /SHARED,
 	the corresponding device is automatically created provided that
 	the process issueing the command has CMKRNL privilege.

 	If the device is specified, and if that device does not exist
 	it will be created as specified.

 	If the optional Logicalname argument is specified a logical name
 	pointing to the device will be created in the process table.
 	Notice that the logical name will not be deassigned when the device
 	is disconnected.

 	Specifying the LD device to connect to is optional, and it works
 	also if an alternate controller is used without a unit number (for
 	example, LDB). So you can let the driver automatically select a
 	unitnumber when it's not specified, so this will work:

 	  $ LD CONNECT DISK.DSK LDB

 	The file will then be connected to the next unitnumber on the B
 	controller.
