If a field is declared as a comp-3 field and if we want to sort a dataset based on this field, then how will the sort card be??? e.g- if we want to sort by a field which is defined as a PIC X(5) then we will mention - sort fields=(1,5,ch,a). Likewise if a field is defined as PIC S9(10)COMP-3 then in this case how will the sort field be defined (because in this case a sign is also involved)???
