hello,
you could try idcams reprop command :
| Code: |
//step0 exec pgm=idcams
//sysprint DD sysout=*
//outfile dd disp=shr,dsn=your-dsn
//sysin DD *
repro filein(outfile) fileout(outfile) skip(500)
|
check in the idcams manual for exact repro command or type on any ISPF panel :
TSO HELP REPRO
or icetool utility may do the same (see in icetool manual)
hope it helps |

if u want to delete first 500 records then use count(500) option.
skip will automatically take the starting value.
if u want to delete last 500 records then use
skip(500)
if u want to delete any particular sequence of records .. suppose from 501 to 600 then use skip(500) count(100)
hope this will clear ur doubts |

| If you give SKIP(n), then this will delete first n records and if COUNT(n) is given then this will retain n records from first and delete all other records. Please correct me if I am wrong. |

Hi
Try this code. this code will delete first 500 records from your input file.
| Code: |
//STEP01 EXEC PGM=SORT
//SORTIN DD DSN=Inputfile,DISP=SHR
//SORTOUT DD DSN=Outputfile,all parameters
//SYSIN DD *
SORT FIELDS=COPY,
SKIPREC=500
/*
//SYSOUT DD SYSOUT=*
|
Regards

This is not correct. Its just the opposite.
SKIP(500) will skip the first 500 records (i.e deleted, will not be printed on the output file). Remaining records will be printed.
COUNT(500) will print only the first 500 records and remaining will be deleted.
If you use both SKIP(500) and COUNT(500) then first 500 records will be skipped and next 500 records will be printed remaining records will be skipped |

bnsahoo,
Here is the way to do that.
| Code: |
//STEP0001 EXEC PGM=ICETOOL
//DFSMSG DD SYSOUT=*
//TOOLMSG DD SYSOUT=*
//IN DD DSN=your file,DISP=SHR
//TOOLIN DD *
COPY FROM(IN) TO(ICE1CNTL) USING(ICE0)
COPY FROM(IN) TO(OUTX) USING(ICE1)
/*
//OUTX DD SYSOUT=*
//ICE0CNTL DD *
OUTFIL FNAMES=ICE1CNTL,OUTREC=(80X),
TRAILER1=(' OPTION STOPAFT=',COUNT-500=(M11,LENGTH=5)),
REMOVECC,NODETAIL
/*
//ICE1CNTL DD DSN=&&OUT,
// DISP=(NEW,DELETE,DELETE),
// UNIT=SYSDA,
// SPACE=(TRK,(1,0),RLSE)

Hi,
This code will not copy first 500 records in output file from your input file.
| Code: |
//STEP1 EXEC PGM=IDCAMS
//DDIN01 DD DSN=INPUT FILE NAME
//DDOUT01 DD DSN=OUTPUT FILE NAME
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
REPRO -
INFILE(DDIN01) -
OUTFILE(DDOUT01) -
SKIP(500) - << THIS OPTION WILL SKIP YOUR FIRST
<< 500 RECORDS IN OUTPUT FILE AND
<< START COPYING FROM 501 RECORDS
COUNT(500)
/*
