A control card can be a member of a pds or a sequential
dataset and is used for storing the date fields, Definitions
of VSAM files....etc. You use control card because you
cannot use a instream procedure in a procedure. Generally
you will be calling a Proc from your Jcl and you cannot code
instream procedure in the Proc and so you will point to the
dataset which is called control card.

Control card used for passing /* ,// as input via inputstream.
if we code //sysin dd * ,we could n't pass /* and // as
input.but if we code //sysin dd data, dlm='xx' ,we can able
to pass..

Answer / susmita

CONTROL CARDS are something that comes into play, where you
can't use sysin dd statement.. for example we can't use
sysin dd * in cataloged procedure. in this case you can
have your instream data under a pds-member and make the
sysin as

//sysin dd dsn=xyz.abc.pos(mem),disp=shr
