I'll trust you that this happened, but I fail to understand how. The default JCL disposition should have been (NEW,DELETE) (does your site somehow have a different disposition?) So: o If the programmer specified unit and volume, allocation should have failed because of duplicate data set on volume. o If the programmer omitted unit or volume, allocation should have created a new data set on a work volume. In neither case would the production data set have been deleted.
