For such tiny local cursors used as join filters you can locally pipe their PKs into a
server.pk IN (client.pk1, client.pk2... client.pk_max)
value_set clause to be used on the server in the where-clause.
Select Users.email ;
	From Jobs  ;
		Join Users On Jobs.quoted_by = Users.emp_num ;
	Where qty_recd <> before_qty_recd ;
              and Jobs.job_num in (&CSV_ListOfValuesProducedLocallyIntoString)
	Order By 1 ;
	Group By 1 ;
