Answer / suputhru
meenu u r corrrrect.
STEPNAME.DDNAME DD PARAMETERS;
in place of parameters we can write the parameters which we want to override
//PROC1 PROC
//STEP1…..
//DD1 DD DSN=FILE1,DISP=SHR
…
…
//
Now we can override dd parameter disp=shr to DISP=OLD.
//JOB1 JOB..
//PROCLIB…
//STEP001 EXEC PROC1
//STEP1.DD1 DD DSN=FILE1,DISP=OLD.
SYMBOLIC parameters: used to orverride parameters on the DD statement.
They can be used in cataloged and instream procs.
//ddname DD ¶meter
Values assigned at proc and exec statements.
//JOB1 JOB..
//PROC1 PROC DISPO=NEW ----here dd parameter value assigned at proc.
//STEP1 EXEC PROC1
//DD1 DD DSN=FILE1,DISP=&DISPO ------it means DISP=NEW.

Answer / sj@iy
Adding to that..
Parameters can be overridden on the EXEC statement in
addition to the DD statement.
Sample for overriding REGION parameter of STEP10 in PROC
//STEP10 EXEC PGM=Program1, REGION=56K
//*Overriding the REGION parameter for STEP10
//SAMPPROC EXEC PROC=PROC1, REGION.STEP10=72K
