Why do you use a control card?

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.

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.

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.
