I have a program which must be executed if the given file is having any record. How I can identify if a file is empty or not in a JCL without using a COBOL program?

praveenpurushottam,

You can insert the following code before executing the program step.

//STEP01R EXEC PGM=IDCAMS RC = 4 IF FILE IS EMPTY
//SYSPRINT DD SYSOUT=*
//IN1 DD DSN=Give your input file,DISP=SHR
//OUT1 DD DUMMY,
// DCB=(RECFM=VB,LRECL=2356)
//SYSIN DD *
REPRO INFILE(IN1) OUTFILE(OUT1) COUNT(1)
/*
//*
//STEP02R EXEC PGM=PROGRAM,COND(4,EQ)
//SYSPRINT DD SYSOUT=*
- - - -- - - -
- - - -- - - -
- - - -- - - -

If the input file for the step is empty....... the next step STEP02 wont execute........

Thanks,
