ICL 1900 Series George 3 Operating System Commands

ATTRIBUTE (AU)

Function

Connects a peripheral property with a particular unit on the installation.

Format

ATTRIBUTE peripheral description,PR property name

Forbidden contexts

NOT OPERATOR, REMOTE

Execution

Checks are made that the property name specified is known to the system and is not the special property CENTRAL; that the unit referred to exists; that not more than 5 attributions have already been made to that unit; and that this ATTRIBUTE will not result in more than one EXCL property being ATTRIBUTEd to the named peripheral.

If, however, the specified property is a console property, the effect of the command depends on whether the named peripheral is local or remote. If it is a local peripheral, a command error is generated. If it is a remote peripheral, a check is made that the device concerned does not already have a console property ATTRIBUTEd, otherwise a command error is generated.
