bprasanna,

How do you identify the block to be copied?

Hi Kolusu,
The block starts always with 'aaaa...' .
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

and the second line will be 'ark'

ark

After that there might be 'n' number of 'a's .

a
a
.
.

Finally the block ends with 'aaaa...'

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa


Thanks
Bprasanna

bprasanna,

If 'aaaaaa' is a fixed string which completes the block then the following DFSORT/ICETOOL jcl will give you the desires results.

Code:

//STEP0100 EXEC PGM=ICETOOL             
//TOOLMSG  DD SYSOUT=*                 
//DFSMSG   DD SYSOUT=*                 
//IN       DD *                         
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
ARK  -PICK01                           
A    -PICK02                           
A    -PICK03                           
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
ACK                                     
A                                       
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
ARK -PICK04                             
A   -PICK05                             
A   -PICK06                             
A   -PICK07                             
A   -PICK08                             
A   -PICK09                             
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA     
//OUT      DD SYSOUT=*                                     
//TOOLIN   DD *                                             
  SPLICE FROM(IN) TO(OUT) ON(81,8,CH)         -             
  WITHALL WITH(1,80) KEEPNODUPS KEEPBASE USING(CTL1)       
//CTL1CNTL DD *                                             
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),       
        IFTHEN=(WHEN=(1,3,SS,EQ,C'AAA,ARK'),               
       OVERLAY=(81:SEQNUM,8,ZD,1,3)),                       
        IFTHEN=(WHEN=NONE,                                 
       OVERLAY=(89:SEQNUM,8,ZD,                             
                81:81,8,ZD,SUB,89,8,ZD,M11,LENGTH=8))       
                                                           
                                                           
  SORT FIELDS=COPY                                         
  OUTFIL FNAMES=OUT,REMOVECC,BUILD=(01,80),                 
  INCLUDE=(89,3,CH,EQ,C'ARK'),                             
  SECTIONS=(81,8,                                           
  HEADER3=(80C'A'),                                         
  TRAILER3=(80C'A'))                                       
/*                                                         


The output from this job is

Code:

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
ARK  -PICK01                       
A    -PICK02                       
A    -PICK03                       
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
ARK -PICK04                         
A   -PICK05                         
A   -PICK06                         
A   -PICK07                         
A   -PICK08                         
A   -PICK09                         
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA


Hope this helps...

Cheers

You can do this kind of thing more easily and efficiently 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 DSN=...  input file (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN    DD    *
  OPTION COPY
  OMIT COND=(1,3,CH,EQ,C'AAA')
  INREC IFTHEN=(WHEN=GROUP,BEGIN=(2,1,CH,NE,C' '),
    PUSH=(81:1,3,84:ID=8))
  OUTFIL REMOVECC,
    INCLUDE=(81,3,CH,EQ,C'ARK'),
    BUILD=(1,80),
    SECTIONS=(84,8,
      HEADER3=(80C'A'),
      TRAILER3=(80C'A'))
/*


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