 Posted: Mon Jun 09, 2003 7:57 pm Post subject: EZT Program - Urgent |
 |
|
Hi ,
I need help with an EZT program for file compare.
filea:
10
30
30
40
fileb:
20
30
40
I wan't to copy all the records from filea that have a matching record in fileb in one file and all records in filea that don't have a matching record in fileb in another file.
Note: filea has duplicates.so 2 records with "30" should show in the matched output.
I've to use EZT only.
Please help

mikemurray,
This should accomplish what you want (MAKE SURE YOUR INPUT FILES ARE SORTED):
| Code: |
//EZPLUS EXEC PGM=EZTPA00
//STEPLIB DD DSN=LOCATION OF YOUR EASYTREV LOADLIB,
// DISP=SHR
//SYSPRINT DD SYSOUT=*
//FILEB DD DSN=FILEB,DISP=SHR
//FILEA DD DSN=FILEA,DISP=SHR
//OUTPUT DD DSN=OUTPUT,
// UNIT=DISK,
// DISP=(NEW,CATLG,DELETE),
// DATACLAS=FBSML,
// LRECL=80
//OUTPUT1 DD DSN=OUTPUT1,
// UNIT=DISK,
// DISP=(NEW,CATLG,DELETE),
// DATACLAS=FBSML,
// LRECL=80
//OUTPUT2 DD DSN=OUTPUT2,
// UNIT=DISK,
// DISP=(NEW,CATLG,DELETE),
// DATACLAS=FBSML,
// LRECL=80
//SYSIN DD *
FILE FILEB
NUMB 1 02 A
*
FILE FILEA
NUMA 1 02 A
*
FILE OUTPUT
*
FILE OUTPUT1
*
FILE OUTPUT2
*
JOB INPUT (FILEB KEY(NUMB) +
FILEA KEY(NUMA))
IF MATCHED
PUT OUTPUT FROM FILEB <==ONLY MATCHED RECORDS WILL APPEAR ON THIS FILE
ELSE
IF FILEB
PUT OUTPUT1 FROM FILEB <==RECORDS ONLY ON FILEB WILL APPEAR HERE
ELSE-IF FILEA
PUT OUTPUT2 FROM FILEA <==RECORDS ONLY ON FILEA WILL APPEAR HERE
END-IF
END-IF
/*
|
RESULTS:
OUTPUT
30
30
40
OUTPUT1
20
OUTPUT2
10
There are many other ways to do this but this is what I would use.
Good Luck!

dalaly,
Does EZT's Synchronized file processing takes care of duplicates? |

Premkumar,
As long as your driver file has unique records in it and both files are sorted prior to executing your program, EZT will process duplicates correctly.
Best regards,

Hi Dalalay ,
Thx for the solution.If possible can u post the soluiton for this without using synchronous input(i.e using JOB INPUT NULL).The output should be the same.

Use this for Input NULL
**
| Quote: |
JOB INPUT NULL START INIT-PARA
IF EOF FILEA
STOP
END-IF
IF EOF FILEB
IF NOT EOF FILEA
GET FILEA
GOTO JOB
END-IF
END-IF
IF KEY-A = KEY-B
PUT FILEC FROM FILEB
GET FILEB
GOTO JOB
END-IF
IF KEY-A LT KEY-B
GET FILEA
GOTO JOB
END-IF
IF KEY-A GT KEY-B
GET FILEB
GOTO JOB
END-IF
*
INIT-PARA. PROC
GET FILEA
GET FILEB
END-PROC
**
