Top

Device description (DEVD)

Specifies the name of the device description.

This is a required parameter.

Remote location (RMTLOCNAME)

Specifies the remote location name of the system with which this object communicates.

*NONE

There is no remote location name. This device can represent any remote location.

remote-location-name

Specify the remote location name, remote system name, or internet address.

Online at IPL (ONLINE)

Specifies whether this object is automatically varied on at initial program load (IPL).

*YES

This device is varied on automatically at IPL.

*NO

This device is not varied on automatically at IPL.

Attached controller (CTL)

Specifies the name of the controller description to which this device is attached.

Note: To use this device for communicating with a remote location that resides on the same system as the local location, specify a controller description that was created with LINKTYPE (*LOCAL) specified.

Text 'description' (TEXT)

Specifies the text that briefly describes the object.

*BLANK

No text is specified.

character-value

Specify no more than 50 characters of text, enclosed in apostrophes.

Authority (AUT)

Specifies the authority you are giving to users who do not have specific authority for the object, who are not on an authorization list, and whose group profile or supplemental group profiles do not have specific authority for the object.

*CHANGE

The user can perform all operations on the object except those limited to the owner or controlled by object existence (*OBJEXIST) and object management (*OBJMGT) authorities. The user can change and perform basic functions on the object. *CHANGE authority provides object operational (*OBJOPR) authority and all data authority. If the object is an authorization list, the user cannot add, change, or remove users.

*ALL

The user can perform all operations except those limited to the owner or controlled by authorization list management (*AUTLMGT) authority. The user can control the object's existence, specify the security for the object, change the object, and perform basic functions on the object. The user also can change ownership of the object.

*USE

The user can perform basic operations on the object, such as running a program or reading a file. The user cannot change the object. Use (*USE) authority provides object operational (*OBJOPR), read (*READ), and execute (*EXECUTE) authorities.

*EXCLUDE

The user cannot access the object.

*LIBCRTAUT

The system determines the authority for the object by using the value specified for the Create authority (CRTAUT) parameter on the Create Library (CRTLIB) command for the library containing the object to be created. If the value specified for the CRTAUT parameter is changed, the new value will not affect any existing objects.

name

Specify the name of an authorization list to be used for authority to the object. Users included in the authorization list are granted authority to the object as specified in the list. The authorization list must exist when the object is created.

Examples

CRTDEVASC   DEVD(ASC001)  RMTLOCNAME(NYC)  CTL(CTLASCNYC)

This command creates an asynchronous communications device. The device is located in New York City and is attached to controller CTLASCNYC.
