USER: Validate Totals

DSPTRN, like EDTTRN, gives you an extra user point before you press Enter. This allows you to perform useful validations; in particular, relational checks between a DBF field and a function field. An example is, a comparison between a customer’s credit limit and his outstanding balance plus an order total in an Order Entry function. You can then set the program context defer confirm field to not confirm, PGM.*Defer confirm = *Do not confirm, if the validation fails and you do not want DBF updates to occur.
