<numeric expression>

The name index number for a variable. You can determine the name-index number associated with a particular variable by the position of the variable record in the Variables module.

Example

.In the example below, parts of different types arrive at location In_Queue. Each entity type has a unique value for Attr1 that corresponds to the name-index number of a variable in the Variables module. Once parts arrive at In_Queue, they increment the variable specific to that entity type before routing to the location Process_Loc.
