the logic to compare two files is here

the code is written in COBOL but should not be difficult to code the equivalent for a different language

I am preparing for an interview and normally this question is being asked in interview..
Appreciate your views.. Any help.... Thanks for your help.

Hello,

As Enrico suggests, look at the topic he provided a link to.

This bit of code is rather straight forward and will work in every procedural language i've ever used.

If you see something that is not clear to you, post your doubt here.

To compare Adabas file contents, I would extract the data via Adabas utility or Natural program, and pass the extracts to SuperC.

I wouldn't consider the posted COBOL program to be equivalent to a comparison, but if you need such a thing, a "Natural sequential match" program has been available for download for years. I know because I posted it.

If you don't need to see field value differences, just to know if two files are equivalent, then I recommend a "Natural checksum" program. An example is available for this, too.
