Control card is a Dataset
A "control card" may be a dataset or it may be inline.
The use of the control card(s) is to provide run-time processing control information to the process that is being run. One example is sort control information that tells the sort which columns to operate on and what to do. Another example of "control cards" is the idcams statements to delete/define a vsam cluster.
