Answer Posted / 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.

thn please share with us. Thanks
