Sort Detail records with Header & Trailer

Postby purva » Fri Feb 17, 2012 2:23 pm

Hi,

I have one sequential file (LRECL=80) with the below record structure:

HH -------> Header Record
AS,Empid1,H,N,current date,22:00,06:00-----> Detail record
JR,W,22:00,05:00,D008,S9518 ------> All JR records are part of the AS record.
JR,L1,05:00,05:30,D008,S9518
JR,W,05:30,06:00,D008,S9518
AS,Empid2,H,N,Previous date,22:00,06:00-----> Detail record
JR,W,22:00,05:00,D008,S9518 ------> All JR records are part of the AS record.
JR,L1,05:00,05:30,D008,S9518
JR,W,05:30,06:00,D008,S9518
TT ----------> Trailer record

The requirement is to sort the only AS records in detail record in ascending order by Empid & current date.
The file is currently having records in random order.
Emp id position is position is AS record is 5, length 7
Date filed position 13, length 8.

The output file should have the header & trailer as it is. And the format should be like the existing file but only in ascending order of AS record.



Appreciate your help!

Thanks,
Purva

purva,

Use the following DFSORT JCL
//STEP0100 EXEC PGM=SORT                                           
//SYSOUT   DD SYSOUT=*                                             
//SORTIN   DD *                                                     
HH -------> HEADER RECORD                                           
AS, EMPID02,20120216,22:00,06:00-----> DETAIL RECORD               
JR,W,22:00,05:00,D008,S9518                                         
JR,L1,05:00,05:30,D008,S9518                                       
JR,W,05:30,06:00,D008,S9518                                         
AS, EMPID02,20120215,22:00,06:00-----> DETAIL RECORD               
JR,W,22:00,05:00,D008,S9518                                         
JR,L1,05:00,05:30,D008,S9518                                       
JR,W,05:30,06:00,D008,S9518

//SORTOUT  DD SYSOUT=*                                             
//SYSIN    DD *                                                     
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:C'1')),                       
  IFTHEN=(WHEN=GROUP,BEGIN=(1,2,CH,EQ,C'AS'),PUSH=(82:5,7,13,8)),   
  IFTHEN=(WHEN=(1,2,CH,EQ,C'HH'),OVERLAY=(81:C'0')),
