Hi,

I would like to merge two files.
For ex. FILE-A has two fields like SSN and Year-to-date-contribution.
FILE-B has two fields like SSN and Quarterly-Contribution.

FILE-A
-------

101010101 1000.78
202020202 2000.13

FILE-B
--------
101010101 1004.78
202020202 2010.13


Now, i have to do the calculation like Year-to-date-contribution (-) Quarterly-contribution based on the SSN.

i.e., my output would contain SSN and TALLY fields.


FILE-C
--------
101010101 0004.00
202020202 0010.00



Can you please give your valuable inputs in this.


Thanks in advance
Syam

Syam

First let me explain how i understood your requirement, and coded the JCL.If my understanding is wrong please correct me.

Say I have 2 input files , where i am considering first 2 bytes as my key

10 01 -> FILEA REC

10 19 -> FILEB REC

In step01 of my jcl i would generate a new FILEC which has data like

10 01 19 -> FILEC REC ( Ideally i am trying to build one rec for each key)

And then in step2

I would subtract 19 from 01 and genrate a new file FILED which has data

10 18 ----> FINAL OUTPUT.

Please find the JCL for the same below.

//TESTJCLX JOB (AAAA,04,T,0000),'SORTT',CLASS=C,MSGCLASS=T,
// NOTIFY=AAAAA
//*
/*JOBPARM L=9999
//*
//JOBLIB DD DSN=AAAA.PPROD.LOAD,DISP=SHR
//*
//STEP01 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*

//OUT DD DSN=AAAA.TEST.SPLOUT,
// DISP=(,CATLG,DELETE),
// UNIT=SYSDA,
// SPACE=(CYL,(1,2),RLSE),
// DCB=(RECFM=FB,LRECL=8,BLKSIZE=800)
//LIST1 DD SYSOUT=*
//TOOLIN DD *
COPY FROM(IN1) TO(TMP1) USING(CPY1)
COPY FROM(IN2) TO(TMP1) USING(CPY2)
SPLICE FROM(TMP1) TO(OUT) ON(1,2,CH) WITH(7,2)
//CPY1CNTL DD *
OUTREC FIELDS=(1:1,2,4:4,2,7:2X)
//CPY2CNTL DD *
OUTREC FIELDS=(1:1,2,7:4,2)
//*
//STEP02 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//*
//IN1 DD DSN=AAAA.TEST.SPLOUT,
// DISP=SHR
//*
//OUT DD DSN=AAAA.TEST.SPLOUT1,
// DISP=(,CATLG,DELETE),
// UNIT=SYSDA,
// SPACE=(CYL,(1,2),RLSE),
// DCB=(RECFM=FB,LRECL=5,BLKSIZE=500)
//LIST1 DD SYSOUT=*
//TOOLIN DD *
COPY FROM(IN1) TO(OUT) USING(CPY1)
//CPY1CNTL DD *
OUTFIL FNAMES=OUT,
BUILD=(1,3,(7,2,ZD,SUB,4,2,ZD),EDIT=(TT),SIGNS=(+,-))

Note : This jcl can be modified as per your LRECL of files and field
positions.

Thanks
Veera.
