Many readers here are too young to have done any great number of SYSGENs, but they provide an apposite vehicle for discussing such operations. SYSGENs were many-step jobs; and they often failed, not least frequently because the space required in some [real] DASD dataset had been underestimated and that available had been exhausted. IBM provided a utility for reconstituting a job beginning with step n > 1, but it was appropriate indeed essential to delete many already allocated DISP=NEW datasets before rerunning it. It was standard practice to restore the status quo ante by doing so before retrying the SYSGEN, and there are analogous situations in which this should still be done. A tabula rasa is unproblematic, and the deletion of a non-existent data set is an innocuous operation.
