Answer / deepak gairola
Cataloged procedures in JCL can not have instream data(we
can't Use SYSIN DD * statements), so the data needed to
pass to them is put into a Control Card.
Control Card is an element in a PDS.
Means:
The input that we need to give to a procedure like sort
fields..record feilds to be processed are generally put in
the pds member and this is specified in the jcl procedure
as
//ddname dd dsn=pdsname (member)
This member is called a control card
Similarly, you can also pass the data through the SYSIN
parameters.

"Control cards" come in many flavors. . . There are control
cards for the sort, most utilities, and many application
programs.
