You can use SORT program to write current date into a file and then read it into your program. Try running this:
//SORT EXEC PGM=IERRCO00
//SYSOUT DD SYSOUT=*
//SORTIN DD DUMMY,RECFM=FB,LRECL=80,BLKSIZE=80
//SORTOUT DD DISP=(,CATLG),DSN=yourid.DATECARD,
// UNIT=3390,SPACE=(TRK,1),VOL=SER=dasd
//SYSIN DD *
OPTION COPY
OUTFIL HEADER1=(DATENS=(MD4),TIME=(12.))
//*

I'm curious to know why you'd want to pass a system date to a program when the program can just as easily retrieve the system date itself. What is the supposed advantage here?

Actually in the cobol program logic that processes date as an external parameter should be replaced with a logic that uses date from a system.
the problem is not with jcl...
so plz tell me what should be the logic???

Hi Supriya,
Since you have gone through the program, you understood how the date is handling currently.. we dont know how the date handled now and hence cant provide a solution until we see the piece of code handling the date currently. Looks like you have concern pasting the code in the forum, probably you can mask the values and change the variable names and make it as generic.

Are you changing the method simply because you don't understand the current logic?
Are you certain you always want the system date? What if you need to rerun yesterday's job?
Of course, all we can do is guess since the use of the date is not very well explained.
