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

Answer / swapnilkumar

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.

THERE IS ONE STEP AS BELOW: //STEPJS060 EXEC PGM=XYX, COND=((200,EQ,JS010),(0,NE,JS020.C),EVEN) COULD ANY ONE EXPLAIN HOW COND PARAMETER WORKS HERE? I AM CONFUSED BECOZ OF "EVEN".

If a field is declared as a comp-3 field and if we want to sort a dataset based on this field, then how will the sort card be??? e.g- if we want to sort by a field which is defined as a PIC X(5) then we will mention - sort fields=(1,5,ch,a). Likewise if a field is defined as PIC S9(10)COMP-3 then in this case how will the sort field be defined (because in this case a sign is also involved)???
