ASSIGN
(KMON)
Associates the logical name you specify with a physical device or a previously defined
logical-device name.
Format
ASSIGN device-name: logical-device-name:
Parameters
device-name
Specifies either a physical-device or a logical-device name.
• Physical-device name
The standard RT–11 permanent name referring to a particular device
installed on your system. Table 3–1 lists these names. (The colon that follows
the device name is optional.)
• Logical-device name
A logical-device name previously defined (one that is currently assigned to a
physical device).
logical-device-name
Specifies either a logical-device name or the catch-all device assignment.
• Logical-device name
An alphanumeric name, from one to three characters long and followed by an
optional colon that you assign to a particular device.
• Catch-all device
If your monitor has extended device-unit support, in place of the second
ASSIGN parameter, you can specify an asterisk (*) to assign device-name
as the catch-all device. This device becomes the destination for all device
references to undefined device names. See the Extended-Unit System-
Generation Option section in the following command description for further
information on the catch-all device.
Description
Assigning a logical name to a physical device simplifies programming by allowing
you to write device-independent programs. When you write a program, for example,
you can request input from a device called IN and direct output to a device called
OUT. Each time you execute the program, you can assign those logical names to the
physical devices you need to use for that job.
