| What kind of "VSAM" -- ESDS, RRDS, KSDS, LS/MFT? |

IDCAMS :
REPRO SKIP(10)
Works only for the 1st 10 records. |

So it's the key.
Do you want to delete records with certain key values, or values of other fields, or just a certain number of records, or records at random, or what?
You say you want to delete 10 records. In that case, what does the key matter?
Clearly think about what you want, and then say so as clearly and unambiguously as you can. |

Review IDCAMS "FROMKEY" and "TOKEY" keywords, which can be used to copy a portion of an INFILE (your KSDS) to an OUTFILE.
You may have to use these multiple times, bypassing the records that you don't need.
Specify a temporary/catalogued QSAM flat-file for your OUTFILE and review the contents after you've completed the copy.
But, backup your KSDS file beforehand.
After review, if the FROM and TO key criteria work as you've expected, then just REPRO the flat-file contents into the KSDS file with REPLACE.
At a later point in time, you can delete the KSDS backup and the temporary/catalogued files.

I've two inferences from this:
1. Delete first 10-records from the VSAM-file -- If this is true - then mention about "column 1 until 12" is useless.
1. Delete first 12-bytes of first 10-records from the VSAM-file and copy the rest in output file as is -- may be repro the VSAM to QSAM, use SORT to do what you've asked for and repro back the sortout to VSAM. |
