1) Use IDCAMS
SYSIN DD *
PRINT INDATASET(file name) COUNT(1)
gives RC 04 if the file is an empty file.
2)Compare the file with a known empty file using IEBCOMPR
utility. Comparing two empty files gives Nonzero RC

There are two ways to check for the file empty or not.
1) With FILEAID
2) With IEBPTPCH
//STEPXX EXEC PGM=FILEAID
//DD01 DD DSN=P1.SEQUEN.INPUT.FILE,DISP=SHR
//DD01O DD DUMMY
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD DUMMY
other is
//STEPXX EXEC PGM=IEBPTPCH
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=P1.SEQUEN.INPUT.FILE,DISP=SHR
//SYSUT2 DD DUMMY
//SYSIN DD DSN=SYS1.CTLLIB(P1CTL),DISP=SHR
where CTL card has
PRINT TYPORG=PS,CNTRL=1
The either of above step gets RC=04 then the file is empty
else if its zero then file has some data in it.

Answer / fred
There are so many ways this can be done.
DFSORT/SYNCSORT
ICETOOL/SYNCTOOL
IDCAMS
FILEAID/FILEMANAGER
IEBPTPCH
ISRSUPC
EASYTRIEVE
Using REXX checking with EXECIO / LISTDSI
Using SORT is the easiest:
//jobcard
//S010 EXEC PGM=SORT,PARM='NULLOUT=RC4'
//SYSOUT DD SYSOUT=*
//SORTIN DD DISP=SHR,DSN=<datasetname>
//SORTOUT DD DUMMY
//SYSIN DD *
SORT FIELDS=COPY
/*
-- RC 4 if Empty
RC 0 if there is data.

Step 1 RC 4 Step 2 Step 3 I want to know the COND parameter which can be coded in step 2 or 3. Step 2 should be executed based on Step 1 RC and Step 3 should not be executed based on step 1's RC
