Sort both files on Name field

Read file 1
Read file 2

If Name_file1 = Name_file2
Perform below PARA until endofboth the files

PARA:
Write to o/p file
Read file 1
Read file 2
End-if
IF Name_file1 > Name_file2
Read file 2
End-if

IF Name_file1 < Name_file2
Read file 1
End-if

Sorry a small mistake in earlier post :

It should be like:

Sort both files on Name field

Read file 1
Read file 2

Perform below PARA until endofboth the files

PARA:

If Name_file1 = Name_file2
Write to o/p file
Read file 1
Read file 2
End-if
IF Name_file1 > Name_file2
Read file 2
End-if

IF Name_file1 < Name_file2
Read file 1
End-if

Hello sanjay and wecome to the forums,

Please post a few sample records from both files and the output you want when these files are processed.

I believe the posted code will not handle duplicates as a "hit".

Hi,

As Dick has mentioned, providing your expectations with sample input/output is always good.

However, so far it seems a standard "file-matching" problem; if so, there is a sticky in the COBOL forum for such a COBOL program. With a lilttle modification you should be ready to go, here is the link...

If this is not what you are searching for, please clarify more.
