ADAULD is a standard utility, packaged with Adabas. ADASTRIP is a 3rd-party product, with a separate purchase price. There are situations where file maintenance requires the use of multiple Adabas utilities plus some (Natural) coding. ADASTRIP was created to handle those situations in a single job step with a single utility. ADASTRIP is nice to have, but not a necessity. ---
