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.

Answer / krishna

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

wht is sysudump n sysout,sysprint ?
