I have :
File1:
Rec Length=25
Code:

000038156N274622948048972
000038156Y706784028025244
000065932Y848979845546364
000068763Y848979845546364

File2:
Rec Length =9
Code:

000065932
000001146
000038156
000087453

I want the O/P file as:
File3:
Rec Length =25
Code:

000065932Y848979845546364
000038156N274622948048972
000038156Y706784028025244

A record is fetched from the File2 and is compared with the File1(File2 contains only 9 bytes and only first 9 bytes from the file1 should be compared) and all the matching records are written out(Dups allowed).

I searched this forum to get some knowledge on splice and using the following jcl:
Code:

//jOB CARD                                                 
//STPORB03 EXEC PGM=ICETOOL,COND=(04,LT)                     
//TOOLMSG  DD SYSOUT=*                                       
//DFSMSG   DD SYSOUT=*                                       
//IN1      DD DSN=FILE1,     
//           DISP=SHR                                       
//IN2      DD DSN=FILE2,                   
//           DISP=SHR                                       
//OUT12    DD DSN=OUTPUT FILE,           
//           DISP=(NEW,CATLG,DELETE),                       
//           SPACE=(CYL,(200,200),RLSE),                     
//           UNIT=SYSDA,                                     
//           DCB=(RECFM=FB,LRECL=25,BLKSIZE=25)             
//T1       DD DSN=&&T1,UNIT=SYSDA,                           
//           SPACE=(CYL,(200,200),RLSE),                     
//  DISP=(MOD,PASS)                                         
//TOOLIN    DD *                                             
   COPY FROM(IN1) TO(T1) USING(CTL1)   
   COPY FROM(IN2) TO(T1) USING(CTL2)   
   SPLICE FROM(T1) -                   
   ON(1,9,CH) -                         
   WITH(1,9) -                         
   WITH(1,9) -                         
   TO(OUT12) USING(CTL3)               
 /*                                     
 //CTL1CNTL DD *                       
   SORT FIELDS=COPY                     
 /*                                     
 //CTL2CNTL DD *                       
   SORT FIELDS=COPY                     
 /*                                     
 //CTL3CNTL DD *                       
   OUTFIL FNAMES=OUT12                 
 /*     


This is putting all the repeated records from the File1 only. Its not taking the consideration of File2.
Please suggest.

Thanks,
Thrivikram.

To save a bit of processing power,
Code:

//INFILE   DD DSN=FILE1,DISP=SHR
//         DD DSN=FILE2,DISP=SHR


Try it using ALLDUPS keyword

Using the JCL above, you don't have to copy both files into T1.

Thrivkram ,

Expat,

Your suggestion will NOT work as the OP mentioned that file1 has duplicates. So if you use ALLDUPS parm it will select a NON matching key also.

And SORT does not allow 2 different FB LRECL datasets to be concatenated.

Kolusu,

It's Friday and it's been a long week.
Yeah, I missed the bit about different record lengths. Embarassed

But how will ALLDUPS select a non matching key ?

T,

This syncsort will do what you need.
Code:

//SRTFIL1  EXEC PGM=SORT,COND=(0,LT)                       
//SYSIN    DD *                                             
 JOINKEYS FILE=F1,                                         
           FIELDS=(001,009,A)                               
 JOINKEYS FILE=F2,                                         
           FIELDS=(001,009,A)                               
  REFORMAT FIELDS=(F1:001,025)     *ALL OF FILE ONE ON MATCH
  SORT     FIELDS=COPY                                     
  OUTFIL   FNAMES=MTCH01                                   
//SORTJNF1 DD DSN=your input file1,DISP=SHR                   
//SORTJNF2 DD DSN=your input file2,DISP=SHR                   
//*                                                         
//MTCH01   DD DSN=D.MVSJOIN,DISP=(NEW,CATLG,DELETE)   
//*

expat,

consider the following example

file : 1
Code:

111111
222222
222222
333333
333333


File : 2
Code:

111111
222222


Now if you concatenate these 2 files and look for all dups, you would also get the 33333 record even though it does not have a match in file2

Thrivikram.

Here's a DFSORT/ICETOOL job that will do what you asked for:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG  DD SYSOUT=*
//IN1 DD DSN=...  input file1 (FB/25)
//IN2 DD DSN=.... input file2 (FB/9)
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//OUT DD DSN=...  output file (FB/25)
//TOOLIN   DD    *
COPY FROM(IN2) TO(T1) USING(CTL1)
COPY FROM(IN1) TO(T1) USING(CTL2)
SPLICE FROM(T1) TO(OUT) ON(1,9,CH) -
  WITHALL WITH(1,26) USING(CTL3)
/*
//CTL1CNTL DD *
  INREC OVERLAY=(26:C'BB')
/*
//CTL2CNTL DD *
  INREC OVERLAY=(26:C'VV')
/*
//CTL3CNTL DD *
  OUTFIL FNAMES=OUT,INCLUDE=(26,2,CH,EQ,C'VB'),
    BUILD=(1,25)
/*
