Hello all,

I have a requirement of splitting a single file into multiple files:

My input file has the layout:

Header1
Record1
Record2
Record3
Record4
Trailer1

Header2
Record5
Record6
Record7
Trailer2

Header3
Record8
Record9
Record10
Trailer3
-
-
-
Header-n
Record-n
Trailer-n

I want my o/p files as:

File 1:

Header1
Record1
Record2
Record3
Record4
Trailer1

File 2:

Header2
Record5
Record6
Record7
Trailer2

File 3:

Header3
Record8
Record9
Record10
Trailer3
-
-
-
File n:

Header-n
Record-n
Trailer-n

Please let me know if it can be done using a JCL utility or should I go for an application program itself.

Thanks,
Binoy.

Try this DFSORT JCL. The first step0100 will create dynamic control cards for allocation and also for splitting. The Second step0200 will create the entire JCL to be execueted. Check the output from step0200, if you see everything is correct then change this statement in step0200

Code:

//SORTOUT  DD SYSOUT=*                       


to
Code:

//SORTOUT  DD SYSOUT=(*,INTRDR)


Code:

//STEP0100 EXEC PGM=SORT
