 |
|
Hi, I have a situation where I need to drop 'unpaired' records based on a 'status' field...
Here is my input:
Key Field Status
1111111111 1D
1111111111 1A
2222222222 1D <- drop record since it has no '1A' record following
3333333333 1D
3333333333 1A
4444444444 1A
I would like to DROP all records (based on key field in bytes 1-10) that
have only a status '1D' record (as in key record 2222222222 from above).
Thanks for any help. |

tcurrier,
Quite simple. Using the following DFSORT/ICETOOL JCL which will give you the desired results
| Code: |
//STEP0100 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD *
1111111111 1D
1111111111 1A
2222222222 1D <- DROP RECORD SINCE IT HAS NO '1A' RECORD FOLLOWING
3333333333 1D
3333333333 1A
4444444444 1A
//OUT DD SYSOUT=*
//TOOLIN DD *
SELECT FROM(IN) TO(OUT) ON(1,10,CH) ON(81,2,CH) ALLDUPS USING(CTL1)
//CTL1CNTL DD *
INREC OVERLAY=(81:12,2,TRAN=ALTSEQ)
ALTSEQ CODE=(C4C1)
OUTFIL BUILD=(1,80)
//* |

Thanks, Kolusu-
The 2222222222 1D record was dropped as expected, but the
4444444444 1A record was also dropped... I only wanted to drop
records if there was a single 1D record.... Thanks. |

tcurrier,
If that is the case then use JOINKEYS, using the same file twice.
| Code: |
//STEP0100 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//INA DD *
1111111111 1D
1111111111 1A
2222222222 1D <- DROP RECORD SINCE IT HAS NO '1A' RECORD FOLLOWING
3333333333 1D
3333333333 1A
4444444444 1A
//INB DD *
1111111111 1D
1111111111 1A
2222222222 1D <- DROP RECORD SINCE IT HAS NO '1A' RECORD FOLLOWING
3333333333 1D
3333333333 1A
4444444444 1A
//SORTOUT DD SYSOUT=*
//SYSIN DD *
OPTION COPY
JOINKEYS F1=INA,FIELDS=(1,10,A)
JOINKEYS F2=INB,FIELDS=(1,10,A)
REFORMAT FIELDS=(F1:1,80)
//*
//JNF2CNTL DD *
OMIT COND=(12,2,CH,EQ,C'1D')
//* |

oops... our shop uses SYNCSORT.... that must be the issue here?

Of course it is an issue as syncsort doesn't support DFSORT syntax and JNF1/JNF2CNTL. I'm a DFSORT developer. DFSORT and Syncsort are competitive products. I'm happy to answer questions on DFSORT and DFSORT's ICETOOL, but I don't answer questions on Syncsort.
You might have to change your jcl to something like this
http://www.mvsforums.com/helpboards/viewtopic.php?p=42970#42970
and move your omit cond to joinkeys
Good luck
