Hi,

My input is something like this:

Code:
ABCD
EFGH
HIJK
LMOP
XXXX
QRST
VWXY


What I want is using Icetool / DFSort, I want all the records which are coming before a fixed string in the file which here is 'XXXX'. Can you please let me know how to do it.

so, output would be:

Code:
ABCD
EFGH
HIJK
LMOP


thanks.

Amit4u79,

try this untested DFSORT/ICETOOL job which will give you the desired results.

Code:

//STEP0100 EXEC PGM=ICETOOL                     
//TOOLMSG  DD SYSOUT=*                           
//DFSMSG   DD SYSOUT=*                           
//IN       DD *                                 
ABCD                                             
EFGH                                             
HIJK                                             
LMOP                                             
XXXX                                             
QRST                                             
VWXY                                             
//OUT      DD SYSOUT=*                           
//TOOLIN   DD *                                 
  COPY FROM(IN) USING(CTL1)                     
  COPY FROM(IN) TO(OUT) USING(CTL2)             
//CTL1CNTL DD *                                         
  OUTREC FIELDS=(1,5,SEQNUM,8,ZD,START=0,INCR=1)         
  OUTFIL FNAMES=CTL2CNTL,                               
  INCLUDE=(1,4,CH,EQ,C'XXXX'),                           
  OUTREC=(C' OPTION STOPAFT=',6,8,80:X)                 
//CTL2CNTL DD DSN=&T1,DISP=(,PASS),SPACE=(TRK,(1,1),RLSE)
/*                                                       


Hope this helps...

Cheers

Kolusu

Amit,

Kolusu's DFSORT/ICETOOL job will work. However, here's an easier, one pass way to do it with DFSORT:

Code:

//S1 EXEC PGM=ICEMAN                                             
//SYSOUT  DD SYSOUT=*                                           
//SORTIN       DD *                                             
ABCD                                                             
EFGH                                                             
HIJK                                                             
LMOP                                                             
XXXX                                                             
QRST                                                             
VWXY
/*                                                             
//SORTOUT      DD SYSOUT=*                                       
//SYSIN   DD *                                                   
  OPTION COPY                                                   
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),             
        IFTHEN=(WHEN=(1,4,CH,EQ,C'XXXX'),                       
                OVERLAY=(81:SEQNUM,8,ZD)),                       
        IFTHEN=(WHEN=NONE,                                       
                OVERLAY=(89:SEQNUM,8,ZD,                         
                         81:81,8,ZD,SUB,89,8,ZD,M11,LENGTH=8))   
  OUTFIL INCLUDE=(81,8,ZD,EQ,+0),BUILD=(1,80)

Frank,

That's a great application. In building on your job, I may have found simpler control cards...

Code:

//SYSIN   DD *
  OPTION COPY
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),
        IFTHEN=(WHEN=(1,4,CH,NE,C'XXXX'),
                OVERLAY=(89:SEQNUM,8,ZD))
  OUTFIL INCLUDE=(81,8,ZD,EQ,89,8,ZD),BUILD=(1,80)
/* 


I think this will produce the same desired output.

Yes, that variation will work in this particular case as well.
