CMPR2

Under CMPR2, any subscripting, indexing, or length calculation associated with id-1, id-10, and id-11 is to be evaluated only once, at the beginning of execution of the UNSTRING statement. However, any subscripting, indexing, or length calculation associated with id-2, id-3, id-4, id-5, id-6, id-7, id-8, and id-9, (or any repetitions) is to be evaluated immediately before transfer into the respective data item.
