Answer / gaurav

Can be obtained using JOINKEYS or ICETOOL

Answer / mdv

Step 1.

Add SEQNUM for both the files @ positions 3 to 8 and 2 to 7
respectively.

Step 2.

Join based on key and reformat as needed.

// SYSIN DD *

JOINKEYS FILE=F1,FIELDS=(3,6,A)

JOINKEYS FILE=F2,FIELDS=(2,6,A)

REFORMAT FIELDS=(F1:1,2,F2:1,1)

SORT FIELDS=COPY

/*

This will meet your requirement.

Answer / nishant singhal

we can do it by cobol pgm also.
File1=1,file2=11 and

fd file3
01 file3-rec
05 ws1 pic 9(1) value zero.
05 ws2 pic 9(2) value zero.

open file1 in inpute mode and write the record in file3
which is opened in output mode. Now open file2 in input and
file3 in IO mode and update the record.

I think it should work.

Muttiah, would you suggest any better approach by using JCL
thn please share with us. Thanks

Answer / muttiah

Nishant,

Thanks for your answer. It's a correct approach to achieve
the result as '111' in file 3..

I'm not sure how this can be done in JCL.

Can someone suggest how this can be achieved.

Answer / ram mohan

@MDV:

I have tested the code. but it's giving Maxcc - 16. Can you
please give us the exact JCL. I feel Joinkeys are not
supporting in the sort which we are using.

thanks in advance.

Answer / msharib

One can try this

//STEP2 EXEC PGM=SORT
//IN1 DD *
1
/*
//IN2 DD *
111
/*
//SORTOUT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD *
JOINKEYS F1=IN1,FIELDS=(1,1,A)
JOINKEYS F2=IN2,FIELDS=(1,1,A)
REFORMAT FIELDS=(F1:1,1,F2:1,3)
OPTION COPY
/*

Answer / muttiah

@satish:

I'm not sure on what basis you have created this jcl. But
if i'm your interviewer i would have blasted you like
anything.

Findings:
1. step1 output will be 1 in postion 1 followed by 001 in
pos 60 - 62.
2. step2 output will be 111 in position 1-3 followed by 002
in pos 60-63. why the hell are you hardcoding sortin in
both the steps and sortout of step2 you are force fully
making it come as '111' because of this
OUTREC FIELDS=1:C'1',2:1
Then what is the case of having step1 if you force fully
making it as '111'..

Coming to step4: i'm not sure what does it mean but i
executed and saw like the output is in this format.
111 in pos 1-3 and 001 in pos 60-62.
Then where are you eliminating 001 in cols 60.

If you are not sure of the answer don't post anything. But
never divert people with your answers. People who are new
to mainframe can feel your answer is correct.

Suppose your program is reading a Sequential Vsam file. The file contains 10 records. How will you code the JCL to read only 2nd, 5th, 7th,and 10th record?
