If devnums specifies more than one device then all devices will have identical characteristics. All devices
defined as a group must be defined on a single channel. A channel is defined as a continuous group of
256 (or hexadecimal 100) devices. For example devices 0010 and 0020 are on the same channel,
whereas devices 0100 and 0210 are not on the same channel.
The devnum itself is either a 1 to 4 digit hexadecimal number in the range 0000 to FFFF for ESA/390 or
0000 to 0FFF for S/370. The device number uniquely identifies each device to the operating system.
devtype is the device type.
argument(s) is a list of parameters depending on the device type. These parameters are explained in the
sections that describe each device type.
Examples:
0120 3380 mvsv5r.120
0230.16 3270 GROUP1 192.168.100.0 255.255.255.0
0583-0587 3420 * maxsizeM=170 eotmargin=131072
