Usinf IDCAMS we can check:

//step01 dd exec pgm=idcams
//sysprint dd sysout=*
//input dd dsn=file name to check, disp=shr
//sysin dd *
print infile(input)character count(1)

if return code is 0, file is not empty

Answer / sivakumar sekharannair

You can use IEBCOMPR
Used to compare two sequential data sets, two partitioned data sets or two PDSEs at the logical record level to verify a backup copy. Fixed, Variable, or undefined records from blocked or unblocked data sets or members can also be compared. However, you should not use IEBCOMPR to compare load modules.
