Hi,

Can the SORT utility be used to sort more than one file within a single step of JCL?

Waiting for inputs....

Thanks,
Jyotsna

Jyotsna,

Here is a sample DFSORT/ICETOOL job which will allow you to sort more than 1 file in a single step.If you have syncsort at your shop then change the pgm name to synctool.

Code:

//STEP0100 EXEC PGM=ICETOOL                         
//*                                                 
//TOOLMSG   DD SYSOUT=*                             
//DFSMSG    DD SYSOUT=*                             
//IN1       DD DSN=YOUR INPUT FILE1,
//             DISP=SHR
//IN2       DD DSN=YOUR INPUT FILE2,
//             DISP=SHR
...
//OUT1      DD DSN=YOUR SORTED OUTPUT1,
//             DISP=(NEW,CATLG,DELETE),
//             UNIT=SYSDA,
//             SPACE=(CYL,(X,Y),RLSE)
//OUT2      DD DSN=YOUR SORTED OUTPUT2,
//             DISP=(NEW,CATLG,DELETE),
//             UNIT=SYSDA,
//             SPACE=(CYL,(X,Y),RLSE)
...
//TOOLIN    DD *
  SORT FROM(IN1) TO(OUT1) USING(CTL1)
  SORT FROM(IN2) TO(OUT2) USING(CTL2)                       
//CTL1CNTL  DD *
  SORT FIELDS=(....)
//CTL2CNTL  DD *
  SORT FIELDS=(....)
  SUM FIELDS=(....)
/*


Hope this helps...

Cheers

having spent more than 20 years in application support I would advise against this type of process. What is gained by having the sort done in a single step. Generally this approach creates more problems than it solves.

I would be interested as to why the requirement to sort multiple files in the same step.

you would certainly be limited in the functionality and flexibility that using 2 sort steps would give you.

just the opinion of a lowly old support programmer who has been "around the block" more than a few times.
