Hi,

I need to sort a file which contains the records as set of lines.

I/P:
0010BBBBB AAA Navigation-Incl trolley
luggage, bags
Tyres,support
0010BBBBB ZZZZZZyard Navigation-Incl lights
new one, support
radio, airconditioning
0010BBBBB MMMMMMMMMMyard Navigation-Incl lights
old one, support
airconditioning
0010BBBBB BBBBBBByard Navigation-Incl lights
common one, support
tape, airconditioning
0010BBBBB AAAAAAAAAAyard Navigation-Incl lights
0010BBBBB KKKKKKyard Navigation-Incl lights

Expected O/P :

0010BBBBB AAA Navigation-Incl trolley
luggage, bags
tyres,support
0010BBBBB AAAAAAAAAAyard Navigation-Incl lights
0010BBBBB BBBBBBByard Navigation-Incl lights
common one, support
tape, airconditioning
0010BBBBB KKKKKKyard Navigation-Incl lights
0010BBBBB MMMMMMMMMMyard Navigation-Incl lights
old one, support
airconditioning
0010BBBBB ZZZZZZyard Navigation-Incl lights
new one, support
radio, airconditioning

Here we need to sort the 2nd column and we need to write the output file with that set of records....

first record :

0010BBBBB AAA Navigation-Incl trolley
luggage, bags
tyres,support
and then the second record:

0010BBBBB AAAAAAAAAAyard Navigation-Incl lights

if i use simple sort then the output for the set of records is not possible.

Yes,i believe it is possible with COBOL only
Please let me know is there any other method by using JCL.

Here I need to sort the 2 column of i/p file after the KEY and based on that i need write the set of lines of records to the output.The set of lines are considered as 1 record and its length may be 3 or 4 continuous lines.

Thanks in Advance,
MK.Kumar.

mk_kumar315,

Are all the "groups" having '0010' in pos 1-4 or do you expect other values also?

mk_kumar315,

If you have Syncsort, you can try out the below job. This assumes an input file of LRECL 80. You can modify it as per your file attributes.
Code:
//STEP1    EXEC PGM=SYNCTOOL                     
//IN       DD DSN= input-file ---- FB,LRECL=80   
//DFSMSG   DD SYSOUT=*                           
//TOOLMSG  DD SYSOUT=*                           
//T1       DD DSN=&&T1,DISP=(,PASS)             
//OUT      DD SYSOUT=*                           
//TOOLIN   DD *                                                       
  SPLICE FROM(IN) TO(T1) ON(89,8,CH) WITH(1,88) WITHALL -             
                  KEEPBASE KEEPNODUPS USING(CTL1)                     
  SORT FROM(T1) TO(OUT) USING(CTL2)                                   
//CTL1CNTL DD *                                                       
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),                 
        IFTHEN=(WHEN=(1,4,CH,EQ,C'0010'),                             
         OVERLAY=(89:SEQNUM,8,ZD,97:11,70)),                         
        IFTHEN=(WHEN=NONE,                                           
         OVERLAY=(89:SEQNUM,8,ZD,89:89,8,ZD,SUB,81,8,ZD,M11,LENGTH=8))
  OUTFIL FNAMES=T1                                                   
//CTL2CNTL DD *                                                       
  SORT FIELDS=(97,70,CH,A,81,8,CH,A)                                 
  OUTFIL FNAMES=OUT,BUILD=(1,80)
