Hi Cindy, 
 Just enclose your output within {} to return multiple values from expression rule. Find the below example 
 load( local!country:"India", local!city:"Nagpur", local!employees:100, { local!country, local!city, local!employees } )

Creating a dictionary on before returning. Then you can reference those values via index(). 
 XXX_getVariableAndLocation() 
 
 with(
 local!tempVariable: rule!XXX_processVariable(), /*** FOR EXAMPLE: RETURNS 5 ****/
 local!variableLocation: rule!XXX_getVariableExpression(),
 {
 value: local!tempVariable,
 location: local!variableLocation
 }
) 
 
 Main Expression 
 
 load(
 local!variableDetails: rule!XXX_getVariableAndLocation(),
 index(local!variableDetails, "value", null)
) 
 
 Output is 5.
