ParametersQualifiers

device-name
 Name of a physical device or a logical name that translates to the
 name of a physical device. The device name can be generic: if no
 controller or unit number is specified, any device that satisfies the
 specified part of the name is allocated.  If more than one device is
 specified, the first available device is allocated.
logical-name
 A character string of 1 through 255 characters. Enclose the string in
 quotation marks (") if it contains blanks. Trailing colons are not
 used. The name becomes a process logical name with the device name as
 the equivalence name. The logical name remains defined until it is
 explicitly deleted or your process terminates.

 /NOGENERIC (default)
 Indicates that the first parameter is a device type rather than a
 device name.  Example device types are: RX50, RD52, TK50, RC25,
 RCF25, RL02.

 /NOLOG
 Displays a message indicating the name of the device allocated. If the
 operation specifies a logical name that is currently assigned to
 another device, displays the superseded value.
