There can be control cards for sort, in which the card may have the details of the field on which it is to be sorted. There are control cards for delete defining VSAM files. These are only a few examples.

A control card (statement) provides information specific to a particular program in a format that the program writer defines.

For example, DFSORT has control statements such as SORT, MERGE, INCLUDE, OMIT, INREC, OUTREC, SUM, OUTFIL, OPTION, etc. These are all defined in "z/OS DFSORT Application Programming Guide".

Other programs and utilities (e.g. IEBCOPY, IEBGENER) have control cards defined for the information those programs need. The specific documentation for those programs give you the definitions for those control cards.

Just to add to the above digression, Contol Cards are PARAMETERS that are passed as Input to the Program. Typically in many IBM utilities like IDCAMS, IEBGENER the SYSIN or SYSTSIN DD will have the Contol cards
