Hello,

I want to sort an input file by section? Can anybody help me to achieve it?

The input file is as below

Code:

77777
55555
66666
22222
33333
*****
11111
22222
44444
33333
*****
88888
77777
*****
44444


The stars are dividing lines. I want to sort each section divided by the lines, i.e. the output file should be -

Code:

22222
33333
55555
66666
77777
*****
11111
22222
33333
44444
*****
77777
88888
*****
44444


Can this be done by DFSORT? Thanks in advance!!

Dragon_Lee,

Just realized that all the tricks mentioned in the above links are kinda of complicated. here are the sort cards for this task.

I assumed that your input is FB recfm and 80 bytes length

Code:

//SYSIN       DD *                                               
  OPTION EQUALS                                               
                                                             
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),           
        IFTHEN=(WHEN=(1,5,CH,NE,C'*****'),                       
                OVERLAY=(89:SEQNUM,8,ZD,                       
                         81:81,8,ZD,SUB,89,8,ZD,M11,LENGTH=8)),
        IFTHEN=(WHEN=NONE,                                     
                OVERLAY=(81:SEQNUM,8,ZD)) 

  SORT FIELDS=(81,08,CH,A,                                     
               01,05,CH,A)                 
                                                               
  OUTREC BUILD=(01,80)                                       
/*

You can now do this kind of thing more easily with the new WHEN=GROUP function of DFSORT available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008) like this:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
77777
55555
66666
22222
33333
*****
11111
22222
44444
33333
*****
88888
77777
*****
44444
/*
//SORTOUT DD SYSOUT=*
//SYSIN    DD    *
  INREC IFTHEN=(WHEN=GROUP,BEGIN=(1,5,CH,EQ,C'*****'),
    PUSH=(81:ID=8))
  SORT FIELDS=(81,8,ZD,A,1,5,CH,A)
  OUTREC BUILD=(1,80)
/*


For complete details on the WHEN=GROUP function and the other new functions available with PTF UK90013, see:
