Hi ,

I have two files who's LREC is different ,when i'm trying to append/merge ,the data is actually copied/over writing the data present in the output file.
below is the code I have used

first file lrec is 50 and second file lrec is 200

the output :some data which is unknown
some data

but the actual required output is
12345678
some data which is unknown
some data

please help me out

//step exec pgm=icetool
//toolmsg dd sysout=*
//dfsmsg dd sysout=*
//input1 dd *
12345678
/*
//input2 dd *
some data which is unknown
some data
/*
//output dd sysout=*
//toolin dd *
copy from(input1) to(output)
copy from(input2) to(output) using(ctll)
/*
//ctllsntl dd *
outrec overlay=(50:X)
/*

What is the RECFM of the files?

Can you give representative sample data for both input files and expected output.

can any one suggest different ways available for merging two files of diffrent lrec

recfm is fb for both the files ,but the thing is lrec is different .
sample input:

file1:12345689

file2:(it contains hell lot of data) for ex
aaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbb
expected output:

12345689
aaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbb

Can you run this, please, and post the SYSOUT from the step, in the code tags like I've done for this JCL.



This will tell us what level of Sort product you have, so we don't spend time thinking of solutions which won't work for you.

What is the DISP on the DD OUTPUT? You need to have DISP=(MOD,CATLG,DELETE) if you need the data to be appended.
