u can use ams command repro thru idcams utility and check 
for rc

Use comparex/ISRSUPC utility and compare ur file with an 
empty file of the same DCB parameter. Retrun code of 28 
means the file is empty. return code of 1 means the file is 
not empty.

IFEMPTY utility is used to check the file is empty or not,
if the return code of this step is 4 then the file is empty.

you can use IEBPTPCH utility.it is used to check whether it 
is empty or not.If the return code is 4 then the file is 
empty.

By IDcams its is possible
// STEP EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//FILE1 DD DSN=INPUT-FILE,DISP=SHR
//SYSIN DD *
  PRINT INFILE(FILE1)
  DUMP COUNT(1)
/*
IF THE FILE IS EMPTY JCL GIVES RC=4

Hi vani,

When i tried executing ur JCL i am getting this error while 
giving JJ.

'DUMP' IS NOT A RECOGNIZED IDCAMS STATEMENT NAME

What shall i do????

First SORT the input file.
Assume the sorted o/p is in MY.SORT.FILE, then run this step

//CHEKEMTY EXEC PGM=IDCAMS                          
//SYSPRINT DD SYSOUT=*                              
//MYFILE   DD DSN=MY.SORT.FILE,DISP=SHR 
//SYSIN    DD *                                     
  PRINT INFILE(MYFILE) CHARACTER COUNT(1)  

if the above step returns a RC=4, then the file is 
empty
