The ‎{attribute 'parameterstringof'}‎ pragma allows the instance name of a specified passing parameter to be made available to the referenced visualization. An interface variable (type: ‎STRING‎) will contain the instance name of the specified passing parameter. The interface variable is visible within the referenced visualization and can be used, for example, in a text output.

Syntax:

‎{attribute 'parameterstringof' := ' <variable> '}‎
