I have a source data file having around 20000 recorrds and need to create some test file with extracted records from the same source file.
So, i want to populate 1st, 5th, 10th ,15th record and so on.... upto 1000..!
Can we use any option from DFSORT utility to create such test file ? |

sampled or better sample is the buzzword
the sequence is mathematically <illogic> the delta is not the same
out of the box dfsort will sample 1,6,11,16,21,... |

Yes Enrico,
a logical error .. my bad... 
It should be with constant delta like you said...
1,6,11,16,21 and so on.. till some limit like 100 or any constant
Thanks. |

Hi,
Check for the sort keyword SAMPLE in manual..
USe SAMPLE along with ENDREC, It will solve your purpose
Thanks,

11111 RECORD 11
11111 RECORD 12
11111 RECORD 13
11111 RECORD 14
11111 RECORD 15
//SORTOUT DD SYSOUT=*

OPTION COPY
INREC IFOUTLEN=80,
IFTHEN=(WHEN=GROUP,RECORDS=5,PUSH=(81:SEQ=1)),

Yes, it worked out for SAMPLED file creation
Control card of job step with program SORT, will work as:
| Code: |
OPTION COPY
OUTFIL FNAMES=OUT1,STRARTREC=1,SAMPLE=5,ENDREC=50
OUT1 will include now record #1,6,11,16,21,26,31,36,41,46 from SORTIN file.. |
